Got a sat nav system to fit this weekend. Can anyone advise me which is the 'speedo signal' wire or best way to find out. The unit needs to pick up from this. Car is a 2003 UK WRX.

Thanks!

 

The following page has pinout for the 2002 - 2003 WRX US model this might help.

I always get the wire from the dash clocks... easiest way... cant remember which colour it is now though! If you havent found it by weekend ill pop my clocks out and check

 

Have had a go at fitting kenwood dv3200 in my 2004 wrx. got it most of it wired but stuck on the speed pulse wire. Any info as to the colour of wire behind the speedo greatly appreciated.

Thanks.

Naz.

 

I had to do mine recently. Found the best place was the Apexi website. It gives a PDF with diagrams of all the connectors (on the ECU) so you can be sure you are connecting to exactly the right one.

I can mail it to you if you want. Just PM me. You need page 37 and 38 by the way.
