Im doing a f22 swap to h22a and reusing my f22 harness. Has anyone done this before? If so what did you have to extend/add. I know the vtec solenoid and knock sensor, but the dizzy wiring is different on the h22 and my shift solenoid wires dont reach, I was hoping I dont have to extend alot but its looking like ill be extending quite a bit.

ill try to bring my build thread from pp.com to this site....

 

You'll have quite a lot soldering. Dizzy, IAT (IIRC), IAB, IACV, KS, VTEC, O2 sensor. A service manual is your best friend in this case.
