ok i just did a b16 swap in a 96 dx hatch body. i used the dx harnest and everything works fine. the problem that i ran into is the car idles like crazy. now the plug on the dx harnest for the iac sensor has 3 wires and its wide. the one on the b16 is 2 wires does any one know how to convert it or how to rewire the iac sensor with the 2 wire plug. help the idle is driving me nutzzzz thanks

 

On my 95 civic I only had a 2 wire on the D series. maybe you can change the plug frpm a B16 harness and follow back to the ecu

 

Im pretty sure you can just use the plug from the b16. Just connect the two wires from the b16 plug to the like colors from the dx harness.

 

thanks guys fixed the problem easy cut and splice
