My son has a 93 civic hatch. It had a d15 non vtec, and we just put in a d16y8. Went to wire the vtec so I looked up the pin out and it says run the vtec wire to A04 its supposed to be a orange with white wire. This car has an orange with black wire. I don't wanna start messing with stuff until I get a confirmation that is still the correct one. Also when putting in the engine he cut the evap purge valve and apparently the d16 harness doesn't have a plug for the purge valve. What wire do I run these to on the ecu? The plug has a red with yellow and a black with yellow wires.
