I'm trying to help a buddy of mine out. He has an 91 CRX Si with an LS swap.

It's got a hack job of a wiring harness, and the guy who sold it to him did some weird, retarded **** to the interior and engine harnesses.

I was looking at getting him a new Si engine harness to adapt to the LS motor the PROPER way this time. Are all 88-91 engine harnesses the same?

And, another question: Is the interior harness swappable as well? Like if we were to swap the engine harness and the under dash harness that matches it, is it possible without re-wiring the entire car?

 

No they are not the same. You are better off finding the same year harness and modifying it of fixing the harness in the car now.

 

hmm, what is different about them?

Curious myself, you know Ryan would know from Ry-Wire.

 

I read the 88's are different. A couple wires are switched between the two main engine bay plugs. not sure about interior.
although when i had my old 91 std hatchback i put on some 88-89 stock tail lights and the plugs were different for the tail lights. I don't know if they were 88 or 89 though.

 

88 dosent have the fast idle wires.... so there is 2 extra wires on the drivers side, blue and blk/yellow. Honda uses a diff plug because it needs more positions on 89-91...

Thats all... oh, and its ez to confuse si and hf harnesses, they are different, ya...

 

I have a 88std but the entire wiring harness in the car is from my old 90 civic si. Their were many differences with the wiring harness especially underneath the dash. I don't remember them all, but I just ended up swaping over everything, fuse box under the dash and bunch of other miscellenous things.
