my 06 wrx tr doesnt have the same.. the 4 pin wires are :black, black/blue,black/yellow,black/white.. and most of the other wires are different.. am i just seeing this wrong or is it different?

[12vpro]

look at the other side of the plug. I looked the stuff up my database and it shows all the same. I cannot confirm the 06 stuff yet, as I have not seen one up close.

ya i checked it out.. theres not really a way to get to the other side of the plug because it sits soo deep under everything and the yellow loomed wire(scary airbags) is wrapped around it so im not going to cut the sleeve its in..
http://forums.nasioc.com/forums/show...2&page=1&pp=25 i have been going by this write up and it seems to work except for that there is.. 2 red/white wires in the keyless entry.. kinda confusing..

As an Installer i would'nt suggest DIY's attempting to install their own remote starters especially in a car with a standard. unless you've see a couple installed cleanly i wouldn't recommend it. i've had to fix some cars where people have wired things wrong and burnt wires, lock modules, and computers. not cheap.

i advise against it myself but there are a lot of peeps here lookin for this info. and if you go with a compustar the autostart is ID10T proof....
