Start off, I'm a newbie to motor swap. Here is my problem. I'm swapping a 97 integra LS engine (5-speed) into my 93 delsol. Yes, complete swap, engine and tranny. But I'm using an obd1 ecu cause the wire from the shock tower to ecu is obd1. Is there a diagram showing me how to repin the wire from the shock tower plug to match the engine harness on the engine which is obd2. Thanks, I hope that is not too confusing.

 

Just buy a conversion harness. I did. It's not worth the hassle and effort to re-pin all those wires. try jdmshit.com or boomslang.us $75-125 depending

 

No need to re-pin anything. The OBD2 Integra engine harness plugs right into your stock harness; the wiring matches right up.

Those conversion harnesses are only for using a different OBD ECU in a different OBD car. They have nothing to do with the engine harness directly. And since the OP has an OBD1 car and is using an OBD1 ECU, it wouldn't do anything for him.
