anybody have a wiring diagram for an si harness? tucking wires on b16 and removed all injector clips from harness, now not sure which colors go to which injectors have red/red, brown/red, yellow/red, and grey/red. thanks

 

Gray/red?

That doesn't sound like stock colors. If look at your old shock tower plug just match up the colors

 

he means since there are two wires to each injector red/blk+red, red/blk+brown, red/blk+yellow

to answer your question, starting at the dizzy side injector it should be wired
1 red/blk+yellow 2 red/blk+grey 3 red/blk+red 4 red/blk+brown

 

i know what wire colors mean. what i was getting at is if the wiring was stock or modified? and you have it backwards, injector #1 is closest to timing belt. it also matters if the car was originally a DX, STD or SI (HF if CRX). this will all play a big role in how your harness was originally wired into the stock shock tower plug.

 

^^^ CRX SI-R build harnesses for $$$ - I would listen to him before the other guy.

OP you need to state a little more information about the car and the wiring setup.

 

its 91 si, stock wiring harness. its a greyish/blue color wire btw.

 

that is correct and I didnt say it was injector number one thats just where I decided to start. those colors are right for his "si harness"

 

Continuity check from ECU to wire end.
Done.

 

ok, blue makes more sense.

 

Injector 1- brown/red -->pin a1
Injector 2- red/red -->pin a3
Injector 3- blue/red -->pin a5
Injector 4- yellow/red -->pin a7

Is that what you mean?

 

yes this is what i need'ed but without the pin numbers, but thats always a plus!
thanks everybody for your help time to get finishd tucking xD

 

you would have had the answer quicker if you had said you needed the ecu pin locations
