Wuz up! Im new to the forums. I was wondering if someone can help. I just got a crx 2weeks ago. My 5th Ef. im doin a wire tuck with a 88 si inner harness. When i got to the engine harness i saw the plugs from the driver side is different. The 90 si engine harness has a big round plug when the other has a small square plug. Help what pin out do i need to do? Thanks Also does anybody have a pair of jdm amber bumper lights 4 sale?

 

You mean the plugs going from the Engine harness and plugging into the underdash?

 

yes. i replaced the 2 injector underdash with the 88 si but the engine harness i got is the 90 si.

 

The HF has 4 injectors, you may have just made more work for yourself.

 

What are you talking about?

OP: Best bet is to sell that engine harness and get the right year. Sure, you could change out the firewall connectors and repin, but I don't know if any diagrams exist to make this easy for you. probably going to have to spend many hours tracing wires directly from the ECU and matching them up to the engine harness. I've done similar and it's not fun at all.
