are you trying to wire up the the wire IACV to a Three wire? i would suggest running a 2 wire IACV, assuming that you are using the whole D16Y7 intake setup, you'll need to change that out to a Different Intake manifold like his old one and then everything should just plug and play. If he tries to even run that POS Y7 intake in a 93 his car will idle like **** do to the fact that his stock PO6 ECU will not read a three wire IACV.
