Hey everyone I need some help here to get my civic running. I got a 99 gsr b18c motor (obd2b) and a OBD1 p72 ecu installed in my 1995 civic dx. I have to wire it up for vtec so i purchased a vtec wiring kit which is turning out to be more of a hassle than helpful. I read in another post that for this kind of swap you need to remove the wire at A20 and connect it to A17 on the ecu connector. But in the kit they give me a wire tap and wire that Im supposed to clip onto the wire already pinned in at A17. This is a pink wire that is supposed to be run to the IAB. My problem is that I know that obd1 p72 ecu uses a negative trigger to activate the IAB so what do I do with the red wire thats in A20 right now? Do I cut it? Also I am supposed to cut the black wire at the IAB and connect it to a 12v switched power source.. but where can I find a 12v switched source in the engine bay?
