Question about apexi avc-r to FD ecu harness
 

I searched a lot, on forums, google, wiring diagram but I'm a little bit confused about 2 things.

I'm ready to tap apexi wire into the fd harness at ecu, but with my searches, I've got only that :

Red wire - power - ecu port 1b wire color B/W
Purle wire - rpm, inj. signal - ?
Gray wire - throttle signal - ?
White wire - speed signal - ecu port 1m wire color G/R
Black wire- ground - ecu port 4c black wire (ecu ground)
Yellow wire - ground - ecu port 4c black wire (ecu ground)

1 - purple wire : can I connect it to any of the 4 injector wire ?
2 - gray wire : It have 3 differant tps wire, I dont remember the ports, but it have one with narrow range, one with full range, and a plain tps one.

:scratch:

The avc-r installation manual tells you exactly what wires to tap into, even shows you the ecu plug and labels it.

Thats the problem, I bought it used and installation manual wasnt included. I download the pdf manuel, buts it tells only in what to tap in, just like I wrote in my previous post.

*from a wrx guy.

It should also come with a Vehicle Specific Wiring Diagram. Since you picked up the EBC used you don't have one. I have the pdf of it on my other computer so here's a link to the scribd of the document. http://www.scribd.com/doc/48999047/PDF-5483 . Pg 18 Z3-b. Remember that this is from the harness side not the ecu. Print out that page and have it with you when you're in the car.

Oh my, thanks a lot ! You have made my day ! :icon_tup:
