I checked out the cruise wiring diagrams and info on Cruise Control on UK STI Spec D, where did these come from? Subaru's UK books, or from another market? Page 107 shows cruise and set indicator lights on the combination meter, don't think these exist on UK cars?

Pete N

Quick update from US, I visited a dealer today and had a quick look at an 07 STI. The cruise command stalk on the steering wheel is different from the stalk shown in our handbooks (for the Oz market car), but it is the same as on UK spec legacy. However when switched on there are indicators on the main instrument panel (in the sector above the DCCD and rev counters, above the left indicator light) for "cruise" and "set" - we do not have these on UK instrument panel so far as I could see. So I would guess our cars are more similar to Oz spec cars which have the cruise on/off switch on the switches next to the fog light switch. I'm going to go back to the dealer again on Monday if I get chance to talk to the parts dept, they were closed today (Saturday).

Above cruise on/off switch looks like this, cheap enough, hopefully same size/shape/connector/function as required on Oz cars, will try to find out more on Monday if i can. http://www.subarupartsforyou.com/cp_...p?partid=10710

PS edited to say, in light of above, it looks like the wiring diagrams on Cruise Control on UK STI Spec D are for a US spec car. gazzer666, can you confirm?

gods_dad

Thank you very much to everyone who has sent me through loads more info. I have posted all of this up on my... ahem... not very good looking website:

Cruise Control on UK STI Spec D

Thanks again and let's keep this going!

weemac2000

Looks to me that what we need are the following:

Uk spec Legacy command stalk
uk spec legacy steerng wheel shroud
possibly...or possibly not...dash mounted cruise control main switch.
All of these should be available from uk dealers.
oh..and someone brave enough to try it out

Does anyone have access to a legacy wiring diagram, so we can check the internals of the switch are the same?

Pete N

weemac2000, command switch layout for the legacy/US spec STI will be as per the pdfs on gods_dad's site. But note that switch has the main on/off switch built into it (the bit on the end that you push in) which is different to the one for the Oz market which does not have that switch - instead the main on/off is on the dashboard.

I think we need more investigation on our cars yet before listing what we need. Haven't found yet what the blank wiring between the fog light and i/c water spray switches is for (cc on/off switch maybe? Not front fogs, heated seats, headlight levelling, so far as I can tell). I didn't manage to get at the steering wheel to see if any connectors there, need to check if clutch and brake switches are present. All the other gubbins downstream of that is needed for other stuff so will be there. And all this assumes the control software is in our ECUs already, any ECU experts out there can confirm either way?

I've spent the last hour looking at the wiring diagrams on gods-dad's site, I'm now convinced they do not represent our cars (more likely for US market). There are too many differences throughout the car. Anyone got wiring diagrams for a UK car?

Pete N

Woohoo! Found some more info. Check this out:

http://ken-gilbert.com/wrx/STi_Manua...%20Control.pdf

From this site, 2004 Subaru Impreza WRX STi, plenty more info on cruise there too if you have a skim through. Best I've found so far, despite not being specifically for an 06/07 model. Still a few questions to be answered as per my posts above.

Now need to sit and digest that lot for a while

marmski

Good work... fingers crossed it might still be possible

gazzer666

Pete you could be right...some of the diagrams are showing right hand drive cars and some are for left hand Canadian models.
I was told that the manuals covered all the basic models. Looks like the OZ model is not covered as they are not showing the 'on/off' switch.
Sorry if there has been any confusion over this.

Latest update.

I got some info from a dealer over here, though as our cars are obviously different from US cars didn't answer a huge amount. The part number for the cruise command stalk is 83151FE020, for same as fitted to US-spec STIs (2004 STI, couldn't find it for 2006/7 car ). The dealer I went to couldn't get one before I leave for home on friday. But on SubaruGenuineParts.com || Where Genuine is Better! (Edited, now correct, thanks Weemac2000!) this part is about $51 plus tax and p&p. I've ordered from this site before and p&p ended up less than quoted, just in case you want to go ahead and order I first saw this site mentioned on NASIOC and as I said I've ordered from them before and they were great.

A search of the oem catalogue on this site also provides most of the rest of what we might need, i.e. a command stalk as shown in our manual (without on/off switch), and switches (dash on/off, brake pedal and clutch pedal) should we need them. The switches were all $20-$30 range and there's a back-plate for the steering wheel at some soppy low price (can't remember exactly, $20-ish), not sure but sounded like the one you'd need if you didn't want to start cutting a hole in yours.

Anyway, all looks cheap enough. Though until I get back home and have another look at my car I'm not prepared to order anything. Then I might attempt piecemeal. Anyone else brave enough to go ahead first?

gods_dad, did you email Subaru Japan with your questions? Probably best place to get ECU information, expecially after Subaru UK's fob-off! The ECU is still the great unknown in all this, does it have the software we need already on there?

Pete.

gods_dad

Update from my side...

I am afraid that I have not heard anything back from Subaru Aus and we know what came back from the UK. As yet, I have not contacted Japan, but might try and look into this.

Just a few comments:

I am not sure that there is a cruise on / off switch on the dash beside the I/C water spray. If you look at the last picture on my site, you can see that in the American spec STI, this final blanking switch is used for the heated seats (Again not an option on the UK version).

From memory, when I last drove one, the Forrester on / off switch was on the stalk and there were no extra switches anywhere. I think this looks like the same setup on the STI stalk (From the picture).

I think the switch for the brake may already be installed as I would imagine they will use the brake light switch.

I think the next stages are as follows:

To remove the steering wheel shroud on an 06/07 STI and see if there is a socket of sorts that the command stalk plugs into. If not, we would appear to be on a road to nowhere.

I think we also need to find out how different the ECU's are. If they are really different, they may well remove the cruise stuff from the UK / Europe ones. If they are not wildly different, it could be more expensive for Subaru to remove the chips etc so they may just leave them in (Which would be good).

The problem I have is that I am currently away from home (So can't remove the shrowd just now) and I am not sure how to find out about the second point!

However, as far as I can see, we may only need the control stalk and possibly the clutch switch if all else is wired in and the socket is in the steering wheel. (Oh and possibly a new shroud that is already cut for the stalk).

Anyone got any thoughts?

Thanks again one and all...

weemac2000

Well Done Pete, ace info.

um, should that be SubaruGenuineParts.com || Where Genuine is Better!

I reckon the command stalk is the same part is the one used in the uk legacy. Might be cheaper/quicker getting it from the uk

Okay, so I am now back home and determined to get further into this tomorrow. My plan is to:

1. See if the clutch switch is in place or if there is a wire where it should be.

2. Same for the brake switch

3. Remove the Steering wheel shrowd to see if I can see the socket that the cruise control stick goes into.

4. See if the fuse panel has a fuse for the cruise control (If there is such a fuse)

5. Scower the STI manual to see if there is any references to Cruise on the UK car

6. See if the wiring matches the diagrams on my site and possibly prod around with a multi tester a bit

7. I wanted to see if the wires were there for the heated seats as I quite fancied getting the switches for these if the wires are there (And again checking the fuse panel). Possibly a bit on the soft side, but the other half likes them in the winter!

If all of this goes well, I am up for buying the command stick and being a guniea pig. I am fairly sure it would be more expensive for Subaru to take out all the cruise stuff than just leave it in and not wire it up and include the control stalk. I might well be wrong, but the control stalk is not expensive and I am happy to give it a go.

I am slightly concerned that the ECU will not have the bits and pieces needed as they may make UK ECU's without the cruise stuff, but nothing ventured, nothing gained and all that...

I would be keen to know how anyone else is getting on if they are trying anything!

gods_dad

Okay, so I had a good old look at the weekend and have posted my write up and pics on my website.

I think we are closer and possibly still some distance off, if that makes sense!

Please do have a read and post your thoughts or comments!

Pete N

gods_dad, I read your update on your website, I don't have broadband where I am at the minute so have not looked at the pics.

I also looked at my car today, at the switches on the pedals. The brake pedal switch only has 2 wires, not 4 as on the cruise wiring diagram. The wires weren't exactly coloured as per the wiring diagram (which shows blue-yellow and white-black for the stop-lamp, but as I didn't write down what they were in the car I've forgotten exactly what they were ), but close enough to identify them as the stop-lamp wires. The 2 wires for the cruise cancel (red-yellow and green-black) are NOT present.

Also I'm not sure the white plastic box with the blue and the grey connectors that you photographed is the ECU (but I don't know what this box is). There's another box to the left of the steering column which I thought was the ECU (but remember I'm a bit of a numpty at all this ). Anyway, from the connectors on this box it looked to me to be more likely to be the ECU, and the numbers on it were: 32520AA180 (looks like a part number to me) and KU11101501 and 0510100932 (don't know what these were and if they're wrong or don't mean anything, bear in mind I was upside down with my head under the dashboard at the time!)

From your investigations and the lack of connector on the steering wheel/column and the lack of wires on the brake switch I think we may be at a dead-end

marmski

weemac2000

The white plastic box with the blue and the grey connectors is the 'body integrated module' . This is basically a glorified junction box that most of the control wiring goes through, including the immobiliser control module under the steering column. The cruise control would pass through here as well, using a green/yellow wire on pin 4 of the grey connector.
There is no 'cruise control ecu' the cruise functions are controlled by the main engine ecu. The command switch takes power from the horn supply on the green connector and the four switch outputs go straight to the main ecu via the othr 4 pins on the green connector. I would surmise that the cruise contral stalk would come with a fully populated green plug which would replace the one already there. The horn supply would then come off that. If I get a chance at the weekend I will try and trace the 4 wires back to the ecu, unless somone elese wants to have a go: the info is all in the wiring diagram pdf.

Slap Head

Any more updates on the cruise control?

with the time i spend on the motorway i'd be interested in fitting this to my car as well

gods_dad

I have to admit to being at a bit of a loss about this now.

The wires are there from the steering wheel, but they don't then seem to be continued to the 'Body integrated module'. If they exit this module, then it could be a case of just patching in the three extra wires and linking the command module to the steering wheel.

I have to admit though at this stage, that it looks to me that more of the stuff is not going to be there (Like the wires Pete is talking about etc). We have no way of finding out if any of the brains is included in the UK / Europe ECU and again, this could easily all be taken out of this spec of car.

If anyone can confirm that the wires are on the other side of the 'Body integrated module', I may be tempted to try fly leads for the missing three wires and buy a US command stalk and just try it.

I have to admit that I don't think it will work, but we have come this far...

If anyone knows anyone with a AUS / US spec STI, it may be worth aksing them to have a look / prod around, but failing that, I can't see any way to progress this.

I am really frustrated to have come this way and be no further forward! ARGH!

scubascooby

All this sounds very familiar. I had a similar experience a few years ago when trying to find a CC kit for my 1997 Sport. It is plug and play and kits were available but I heard there was a recall because the cable became dislodged on some units. As a result Subaru withdrew the kit even though there was a simple fix. Very frustrating.

CRUISE

BIG FUD

iTrader: (84)

Wanted cruise on a subaru for years glad to see this post

gods_dad

All this is good and we did get close, but we don't seem to have got there! If anyone can help, I am still super keen to try and get this working, but just seem to have hit a brick wall.

Does anyone here have a reliable contact at Subaru (Possibly in parts dept) that could maybe fill in a few of the blanks? The main one being if the Cruise stuff is missing from the UK / European spec Impreza ECU's then we really are going nowhere. I don't think it's advisable swapping out ECU's to get this working. If the ECU has the cruise stuff built in, then we could be looking at buying a command module and connecting a few wires. How good would that be?

If anyone can shed any light on this, please do get in touch.

Thanks again,

Tony

How about.....................

Get an OEM stalk from a Legacy (or US spec Sti), OEM steering shroud (with the cut out) and then get someone who's really good with auto-electrics to utilise the OEM stalk with a GoldCruise system.

This way, the bits you can see would be OEM, bu the operating gear would be after-market.

It might just work!!!! I'd suggest that a switch is a switch, so if the OEM stalk has the same number of functions as the GoldCruise ones.......ya never know!!!!

gods_dad

I think that is a good idea, thanks for the suggestion! I have sent the mail below to Conrad Anderson to see if it is at all possible!

Steve,

I am very keen to fit cruise control to my Subaru Impreza STI as I am now having to do a huge number of motorway miles. It is not an option on the car, but oddly enough, it’s standard on the US and AUS cars! I have been posting on a very popular Subaru website to see if it is possible to “Retro fit” the genuine Subaru article, but it appears no one is really sure and it could be really pricey to find out! Just in case you are interested, the post link is here:

https://www.scoobynet.com/lighting-o...i-impreza.html

There are a few things that I hoped you could help me with. The last person on the forum suggested buying the OEM Subaru Cruise stalk and wiring this into the gold cruise unit. This would be my ideal scenario, as this way, it would look like the proper thing and work a treat! I realise that I would need to do some more investigation into if this was possible or not, but I would really like to try and do this. I have wiring diagrams for the Subaru Stalk and can imagine it may be fairly standard…

My next question is, how much would it cost me to fit Cruise to the Subaru? It is a 2.5 litre (Turbo) petrol and I am certain it uses electronic throttle etc. Can you give me an idea of prices if I were to fit it myself? I have done a good bit of auto electrics and think I should be able to fit It myself with a little help from an instruction manual. If it would be too tricky to use the Subaru Stalk I could use one of the ones you offer, but a bit of assistance in trying to fit the Subaru one would be very greatly appreciated. I will also post up my findings to the forum, which could well lead to further orders if it works as many people seem to be interested.

Many thanks for taking the time to read my mail and I look forward to receiving a response.

Kind regards,

Tony Rae

As always, I will keep everyone posted and let you all know the outcome.

marmski

Really hope this comes off... cos i wanted Cruise since like forever!

gods_dad

Had a reply from Conrad Anderson as below:

Hi Tony,

We have done quite a few Subaru's of various types.

With the impreza, the pre 2006 models we would usually do with a AP550 base unit with one of our stalk control units.

For the later 2006 models, we have a fully electronic unit which plugs inline with the existing pedal wiring loom. With using the AP550 on the older models, it can be a bit tricky setting up the unit with the correct stroke length to allow for a nice smooth power curve with no surging.

We would not normally get involved with OE control units as they invariably take more time trying to find the correct pinouts etc and do not give the same functionality. We would prefer to use our command modules which are specifically designed for the unit.

If you have any queries or want to book/ order, please ring 0800 279 6939.

Regards
S.C. Anderson

I then called him up to double check prices and it looks like the below (For 2006 and onwards Imprezas):

We would need the AP803 actuator which is £280.00 (Inc VAT)
We would need the 380T Harness which is £37.50 (Inc VAT)
The cost of the command modules (Stalk) vary from about £35 to £95.

He said that it would likely be possible to link into the OEM Subaru Stalk, but they could not really support or help with this other than provide pin outs for their more basic stalks and we could work out the Subaru ones.

I think the Subaru Cruise stalk takes power from the horn so it could just be a case of matching up wires. It would therefore look like it could be done for about £330 inlcuding carriage, but excluding the cost of the stalk and new steeringwheel shrowd.

What does everyone think?

gods_dad

I decided to order the cruise kit from Conrad Anderson. I have just bought one of the basic control units for the time being and if I get fed up of this, I may look at using the OEM control if this is fairly easy to do. I ordered it on Thursday of last week and they think I should have it in time for the weekend so I can start fitting it.

The total kit comes in at around £375ish including postage which is not very cheap, but it could save many aches and speeding fines!

If anyone is interested, I will try and take photo's and document the process so that others can get an idea of how to (Or not to!) do it.

Tony

v8voodoo

Would be very interested to see photos of progress..

gods_dad

Just a quick update, I ordered the kit on 4th and, as yet, no sign of it. I have called them a couple of times to chase it up and it seems that there is a delay in the delivery from the Netherlands. It's apparently the AP803 (Main control unit) that they have had to order in, but they have ordered a few of them, so if anyone else orders one it should be quicker!

They have promised a call back today to update me and I hope to have it this weekend and get started! Realistically it may be next weekend, but fingers crossed!

I will take photos and notes about the install and post them up when it's all (Hopefully) working!

gods_dad

Conrad Anderson have just called and they think the unit will arrive with them on Monday (22nd) and so I should have it by Wed 24th. I'll hopefully have a go at fitting it that weekend!

spec d

am interested as to how you get on and will keep looking, cruise would be a great addition for those long motorway trips
