ok, i did a b18a swap in my 89 crx dx auto. over by the drivers side shock tower, i've got a plug leftover coming out of the wiring of the engine harness. i used a 1990 integra harness. i've messed around with this plug, and one of the wires, its black and yellow, turns on the engine fan when the car's ignition is in the start position. i've still got this wierd buzzing sound when i try to crank the car, and i've added plenty of good grounds and checked my wiring, and i'm wondering if this has anything to do with it. anyone know what this plug is supposed to plug into or where i have to put the wires that are in it? Also, my ECU light just stays on, and i have a check engine light, and i have no way to read the codes. light just stays solid.

 

Wait, wait wait...
you have a Dx and then you used a 90 integra harness, then plugged all up and the engine doesn't run? Surprised?
I don't know what you have done, but here is what you need to do.
First you MUST use th DX harness.
Conver the DX harnes to MPFI
then plug it all up and try it.
the integra harness will not work with your car. You would need to be a wiring genious to back trace every wire and repin the connections.

 

I second that. You will have these plugs left over on the DX harness when your done:
