need help wiring vtec

[10k]

ok i've been reading and reading on how to wire it up but when i look at a4.. i see it but d6 and d2 im lost right there some pics on where those last two are at would help thanks

edit:this is a cut&paste from superhonda...apparently there are some wire colors that differ among car models but the ecu pins are the same

KEY:
(voltage values measured in DC Volts unless otherwise specified)
V = Volts
Wht = White
Blk = Black
Grn = Green
Yel = Yellow
Brn = Brown
Blu = Blue
Org = Orange

KOEO = Key On Engine Off
KOER = Key On Engine Running

A, B, D= Slot. Numbers are read up and down from left to right, not straight across (see diagram at end).

shit thanks bro thats all i needed

ok i just got done wiring it and im using the p13 and i went to go drive it and it bogs on me on 1 2 and 3 also the knock sensor has two wires one with red/blu and the other one im guessing it a ground right its just wire

[gtaboy24]

I need to wire my vtec for my h22 what pins go to what with p13? 94 si Prelude

Knock sensor should just be one wire, well thats how it is on my Prelude.

This post is nearly a year old. That member doesn't even post anymore, it seems. The guy above you revived this thread.



gtaboy24, are you saying that you have an H22 in a 94 Prelude Si?
The wire colors may not be the same between your car and the cars that this forum focuses on.
The P13 pin layout is in the diagram and list posted above. That's the information you need, right there.
