I have an obd1 ls engine in a 99 civic hatch obd2b with the stock harness and running an obd2b-obd1 harness cant get iacv hooked up properly, orignal iacv on the dx motor was a 3 wire, on the ls motor it is a 2 wire need help!

 

you have to get the plug from a b-series harness for the iacv, and cut the plug of off your stock harness. The colors will match up except that there will one left over wire, its orange.

Edit: You also have to repin the b plug http://www.ff-squad.com/tech/w...g.jpg
