Ok, i started a topic the other day about having problems with my zc swap into my 93 civic......everything did bolt up fine but i found i am left with an extra plug on the harness.....according to the manual it is either the air temp sensor, or one of the two solenoid plugs for the intake exhaust but the problem is.....i only have 2 sensors to plug into on the back of my exhaust manifold......can someone help???

 

Are you throwing codes, or does it not start? I fail to see what the problem is here.

 

What OBD is your wiring harness, compared to the engine?

 

When i think i put them on correctly no codes throw.....but i have one leftover sensor plug......starter turns but the car just won't start......

 

harness is odb1 just like the engine.....
