I have a 96 hatch with a gsr in it but the car came with a 99 wire harness I think but it has no hook up for a 02 sensor so what harness will I need to put in there so it can stop throwing this code the engine lite stays on and i cant get it to throw me the codes.
 
that car should have wiring for 2 o2 sensors (exhaust manifold and cat) if not then its not a 99 or a 96 civic harness. you will probably have to hard wire or lengthen to wiring to the cat (cause im assuming thats the one you are missing). If you have the plug, find the pin outs for the ECU and wire the O2 sensor directly to the ECU.
 
ok I found 1 02 senser its at the end of my dc 4 to 1 header where is the other 1,also on my wire harness that connects to the ecu it only has 2 plugs and there is a spot for the 3 plug how come mine is missing the third one
