Default 3 wire iacv working on obd1???

Ok dude I just finished doing this for my 1996 Civic CX. I am running it with an P75 ECU and it run's great. All you need to do for the IACV 3 wire to work with OBD1 ECU is:

On the OBD2 connector put a Jumper on terminals A12 to A14 and these connect to the A9 terminal on the OBD1 side. The third wire is A13 on the OBD2 connector and it goes to A23 on the OBD1 side.

That's all dude now your friend does not need to change the intake manifold.


Have fun!!!
i found this post on a different forum.. this guy says you dont need to swap your y7 intake with a 2 wire iacv y8.. just connect those pins and it works without any problem... is this true? anyone tried this before??

Yes it works and I have done it. You connect 2 out of the 3 wires and move one at the ecu.
