I have a 2 prong black wire/green wire plug. It is not plugged into anything currently. 96 civic ex running a obd-1 motor.

Looks like that. 2 prong like a iavc plug or iat plug but has 1 green wire and 1 black wire.

thermo switch for the rad fan. The switch screws into the thermostat housing on OBD1/OBD1 engines, OBD0 used a different setup and the switch was on the back of the block and used a different plug.

could possibly be for the power steering switch which if the car does not have power steering its not needed. he would need the thermo switch plugged in for it to operate correctly. so if its running with no CEL i guarantee its the power steering switch plug.

Must be power steering I deleted it when I put in the obd1 engine. Thermo is plugged in. The power steering switch was plugged into the IAVC which caused a cel. Now that I have the correct plug on my IAVC I am still getting the cel even after I reset the ecu via reverse light fuse.

i think it's the hazard fuse under the hood not reverse lights

I think the plug that goes to the power steering is green.

I am getting CEL 14 for IAVC. I was getting this CEL before but I had the mystery plug plugged into my IAVC. Now I have the correct plug in my IAVC and I am still getting the CEL. I have included a picture of the mystery plug.

I am wondering if having the wrong plug on my IAVC has damaged the ECU. The IAVC was fine before the swap.

the 3 plugs on your intake could be mixed up, map, tps, and iavc all have the same plug, easy to mix up
