Well my motor went in my honda civic and it was the d16y7 . So I replaced it with a d15b bottom end and a z6 head. The Iac valve on a z6 head is only a 2 pin connector I believe and the d16y7 is a three pin . How can I convert this into a 2 pin connector can I connect two of the wires? I know someone has done this swap . The ecu is a y8. Basically the iac is not hooked up. When I press in the gas pedal keep it in one position the idle will fluctuate up and down. Drives fine but am looking to sell the car soon and need the problem fixed any ideas?

You'll have to use an intake manifold with a two wire IACV. Any 92-00 D series will work with the exception of 96-00 Auto Y8's and 96-00 D16Y7 engines. The 3 wire and 2 wire IACV aren't electrically interchangeable. Once you get a two wire IACV do this:

I have switched the wire to the approipate spot.Which one be the power wire the the black with blue stripe or the yellow with black stripe? Will this fix my problem with a 97 Ex ecu. Or do I have to get the p28 ecu with jumper harness to work properly?

Yellow with black would have the constant power

with the z6 head ur not going to have a knock sensor either your going to need to mount one to use a p2p ex ecu.

The car starts now with a d15b bottom and and z6 head the ecu im using is a p2p ex ecu. I know there is no knock sensor but the car runs without it. I thought it wouldnt start like that also but it does and has been running like that for a year now.
