I have a 91 civic hatch dx. I have a JDM H22. I have a 90 accord lx harness that was modded to run the h22 in the accord it came out of. The accord harness if for parts ( sensor swaps ).

Im runnning the dx civic harness, Just gonna extend the dizzy wires off my accord wires all the way to the ecu.

And the same for the injectors.

And vtec / IAB

Knock, O2, EGR, are deleted in my tune. No need for those wires.

I identified all the wires on the civic dx harness, but i have this one wire its orange that I couldnt figure out where to swap or if it gets swapped. The device it connected to is called a Tandem Control Solenoid. After research I found it is the early FITV? The vtec luds H22 motor isnt electronically controlled.

Any input would be very helpfull.

 

After research i found its pin B2 on the ecu. thats not used in the convertion harness. So gusse I can remove that pin.
