I have an 89 CRX Si. I bought a while back but it was missing the engine harness.
So I purchased what was believed to be a 89 Si engine harenss.

Everything looks ok. MY question is.. where the wire harness comes
past the timing belt side i have 2 plugs ( a green one for the resistor box ) and a
Square one. But on my car i have the resistor box and a round plug

So i have a square on my engine harness and a round on the firewall.
This is on the drivers side where the resister box resides..

Now the square and round plug seem to be the same ( same wire colors )
just a diff style plug. Can I just repin the right style plug or do I have the
wrong harness and it wont work at all ( hoping I can just repin the one plug )
since I just finished this harness for my OBD1 GSR Swap

Ive Included 2 pictures to help out with what im talking about.





Any Help would be greatly apreciated

I wish I could say for sure... I know that there are differences on the 90-91 harness, and I thought that was one sign of a 90-91 harness(having square pug). You can however easily de-pin, and re-pin on a new round plug, but I wonder about pin placement between years. It seems like it would be the same, because they both use the same computer, and the pin charts I have seen are the same for 88-91, however they could have changed the positions on the plugs (that would be bad). so, if I were you, I would check that. I would get a chart of the crx si ecu pinout, and trace wire colors to the main passesger side firewall. Get a volt meter and knowing by colors what wires are suposed to go where, see if they stay in the same spot.

So this is just an example, say you know that the #1 injector is A1 and has a brwn wire. Find that wire on the main pass side firewall plug, and see if they stay at the same pin placement on the oposite side of the plug. Do this for many if not all of them.

Thats what I would do, also search and see if you can find the differences between the 90-91 and the 88, 89 harnesses.

Thanks Ryan, I will look into that.. Im hoping its just a matter of swapping
and repinning that one plug. Being that the harness is all done loomed and
setup up nice and neat for the OBD1 GSR Swap.

Thanks alot
