I'm just putting a 95 sti type ra together after buying it 90% complete. I seem to have 2 connector blocks from two separate looms running off the gearbox but only one big connector block coming off the engine loom. Can anyone help me work out what's going on? Gearbox code indicates it's the correct box.

 

You sure the smaller plug lives there I recognise it but for the life of me can't think where it goes. What is it attached to?

 

Are you missing part of the loom??

 

I dont think I'm missing any part of the loom, as in that diagram there should be two plugs coming off gearbox. The plug from engine loom cant be for anything else as it's in the same location etc as on my wrx.... thanks for taking a look!

 

Ah yes the two wires connect into one block...maybe I am missing something...but they seem to reach and sit perfectly where they should join engine loom...think I need to get it up on ramp to see better

 

Is item. 24031 a short loom that connects to the 2 plugs, then after a short length connects to the single connector you've got pictured? 🤔

 

If it's the WRXRASTI (lower part of image) the additional plug may be for the DCCD connection side of things.
24031 is the generic "part group" number for that length of cable/loom between the two switches (reverse and neutral position) so maybe different between a WRX and WRXRASTI.
For a WRX the part number is 24031AA080


For a WRXRASTI the part number is 24031AA370
no image found to illustrate.

 

so the two plugs coming off the gearbox go to two separate plugs which obviously dont fit into the one plug coming off the engine bay loom. Am I missing another bit of loom???

 

the neutral position and reverse lamp switches go to an "adaptor" loom which then connects near the pitch mount to the car loom

 

But do they? Has your box got DCCD as per the WRXRASTI section in the diag I posted previously and below..........



If yes the separate smaller connector could be for that and your intermediate cable is "For a WRXRASTI the part number is 24031AA370" for which I can't find an image to illustrate it..
The larger 4 pin plug would be for the reverse and neutral switches, the 2 pin plug for DCCD.



Maybe a post on Type-RA.com may shed some light ??

 

Thanks don I'll check tonight!

 

As Don says above I think I've just checked here for you and that is the DCCD plug which in turn connects to the short loom that goes from the NPS and the reverse light switch to the main connector at the bell housing. You either need that loom or you have DCCD box that shouldn't be in it
So you need the above part no 24031 in post 3 with the extra plug cause the two I looked at here the three plugs go into the one short loom which in turn goes to the bell housing plug.

 

Thanks joe. So I'm writing this as I look ...the two round plugs than come from side of gearbox go into a the larger 4 plug. The dccd 2 wire loom then goes to the smaller plug. So you are saying these two plugs plug into another two plugs that go into one large plug that then plug into engine bay loom?

 

We'll try and make it easy the three plugs at the rear of the box all plug into one loom that goes to the bell housing plug. One of the cars is still on a lift but don't know would I get a picture of it. I'll try if you want. If your box is DCCD I think someone has plugged a wrx loom into the NPS and the reverse light switch because the looms on these two cars go straight from the round plugs and DCCD plug to a six pin connector at the engine loom.
As above in post 10.

 

Here you go.

 

Yeah so I have all six wires.., it's just they go to two plugs rather than one at the bell housing, they dont join and go into one 6 pin plug. Both looms are the correct length to reach the bell housing though so it seems odd if I'm missing an extra bit of loom. What I've just realised is that it's a 96 sti type ra not a 95 (my wrx ra is a 95). Would this make any difference? Still a v2 though.

 

Has your car a DCCD thumbwheel, has the gearbox been changed, have you the DCCD display in the speedometer, what is your model code?

 

Doesn't make any difference.

As 1509joe has said with or without DCCD all six outputs from the gearbox end go to a single 6 pin plug on the bulkhead wiring loom.
Having found and looked at a few old wiring diagrams, the ONLY time I can see a separate 2 pin plug used, is on a N/A box with a AWD-dual range option.
You mentioned at the start the "Gearbox code indicates it's the correct box" what is the code??

 

 

Yes got dccd clocks and thumbwheel

 

You have a WRXRA box not a WRXRASTI one

 

Ahhh...so what are the two wires coming out the top of the box? Where the dccd is located? Surely a wrx box doesnt have two wires coming out the top?

 

You have the wrong loom from the plugs at the rear of the gearbox to the bulkhead.

 

Don just seen this post for a dccd box for sale a while back. Joe do you think gearbox is correct or not?

 

From the info Joe has just pm'd me the DCCD is a retrofit item "off line" so maybe accounts for the extra 2 pin plug which would tally with an early model WRX upgraded to WRXSTI off line.
So if you want to use this box you may need to change the section of loom or make up some sort of hybrid connector.

PM me your VIN and we will see what the database lists for your specific car.

 

Great cheers don. That makes sense. I'm half tempted to drop box out as it's up on my ramp...just to confirm dccd. I'll message you a pic of vin when home from work. Thanks again for all the help!

 

I did notice this car has sound deadening n the floor but I assume this was just an option like electric windows?

 

The STI models only became production line cars from October 1995.


Prior to that they were converted from production WRX's "off line" by STI

 

Hopefully you don't need a box you need a bit of wire 18 inches long. If you had a plug with pigtails which would fit your DCCD plug and then join it up to the bulkhead loom it would work. You could always cut and solder but it's a bit severe. Plus your picture with the four pin connector and two pin connector doesn't really add up. There should be no connector there as Don said that DCCD was retrofitted to that car at the factory so that is possibly the way they did it. If you could remove the short loom from the bulkhead plug to the rear of the box and take a picture it would/could be easily sorted. Ten minutes will remove it. How many WIRES go into your six pin plug at the gearbox end.

 

I'll remove tonight. 6 wires into plug at gearbox end.
