My buddy has a 92 civic which had the d15b7 but blowed it up and bought a d15z1 and I put it in for him and used the wiring harness for the z1 and the ecu so I just need to know how to hook up the vtec?

 

Surely you didn't not search whatsoever.

 

What?

Anyone kno where I can find a diagram on how to wire it up?

 

if you used the z1 harness(which is vtec-e) then it should already have the plugs for the vtec solenoid, which in turn should plug right into the ecu, and you should have vtec... if you didint use the z1 harness, its only a few wires you ned to run to the ecu, and a ground

 

well I used the z1 engine harness and the computer but the vtec still doesn't work??

 

VTEC with that ecu engages ar 2500 rpm so you aint going to hear anything engaging at high rpm, it should sound like its already in VTEC though!

 

Well is there a different ecu that will help it? I mean I know there isn't much help with the z1 it being an economy motor but it should have better power than the b7 and it doesnt

 

Do you have any check engine lights?

 

Yea the check engine light is on

 

I guarantee you he had the wrong ecu.
