Hi all

I'm sure i have seen a thread that said on later impreza's (i.e. 2004 onwards) there was a speed signal connection behind the radio, i have searched for this (before anybody points out the obvious).

So the question is, is there a speed signal wire on the headunit wiring connector ? or do i have to find it on the back of the speedo as i did on my old scooby?

I found my speed pulse here:

Might help you out.

Good luck!

 

Should find it at the ECU which is located behind a metal plate under the carpet in the passenger foot well (in the sloping bit where you stick your feet). I'll try to find the USA site I used.

Found it ! Here you go..........remember the US list UK MY04 as a US MY05. http://www.northursalia.com/modifica...ng/wiring.html

Thanks Guys

 

I think the speed pulse wire is only availble in the radio loom from MY05 onwards.

On my 03 STi I connected it at the ECU as mentioned but on my 06 it was in the radio loom. Either way, very easy to find using the Apexi guide.

 

Thanks Neil, thats just what i wanted to hear , i've just got to get round to taking my new 06 Sti to pieces to fit my headunit, speakers & satnav

PS is the cable the same colour (green/yellow) on the radio loom as it is elsewhere on the car? or at least it was on my 2001 WRX

 

The wire is the same colour green/yellow. It terminates with another wire (I guess was the handbrake wire) into a seperate block but I just earthed the HB wire

 

This is getting better & better and i totally agree about the handbrake connection, whats the point of having satnav & dvd if you cant use them without the handbrake on

once again thanks Neil

You can use the sat nav with the handbrake off its only the dvd/tv that is against the law to have on while your driving. If your pulled over they can check that your handbrake is wired up and if its not then they can give you a 21 day slip.

 

What about passengers in the back watching a dvd then ?

 

I can still use the Sat Nav with handbrake off but with limited options e.g. I am unable to select a new destination from the address book unless the HB is on.

Unit is Pioneer AVIC-X1R

 

In my old WRX i just earthed the handbrake wires for both the headunit and satnav (Kenwood DDX 7025 & KNA DV3200)

 

Sorry to drag this thread up but just about to fit an AVIC-910BT.
Was looking at the extra wires needed for Speed, Reverse and Handbrake.

I notice on MT2007 STi there is a seperate connector with 2 wires.
I think 1 is green/yellow and the other brown (will double check again later).

Are these the speed and handbrake connectors.
As it will save be stripping the car down any further.

P.S if I am correct, does anyone know where the reverse can be connected

cheers

 

I can confirm that this 2-way connector contains the speed pulse and reverse gear selection wires.
Mine was taped to the original loom, with a small 2-way white connector on the end.
