Well since i have a specific question. I couldnt really find it elsewhere. I had gotten a 91 crx si roller. I was missing the engine harness so i went and pick up a si one from the junkyard. Put into the car and well it doenst meet up with the driver side. I have a circle plug in there now. The engine harness has a sqaure plug. Now im thinking the chassis harness was replace. One, the engine harness plug thing. Two, i missing some connectors under the dash. IE. little relay right behind the hood pop, and the clutch pedal. I have no clue what the little relay is.

So is the circle plug from a base, hf model and the square the Si model?

 

There is a difference between 88-89 wire harnesses and 90-91 harnesses. This will not work for you, even if get rid of the clips and put the wires together.

 

Damn. Ok. So the 90-91 harness will have a circle clip on the driver side that hooks up the engine harness?

This car has been mess with. So i dont know if its the stock harness in there.

I have a mini me with a z6 head. Going obd1. Have the rywire conversion. And will be wiring up my own dizzy conversion. Z6 manifold. jdm b16 TB.

Thanks for that. Didnt even think of to check the years. Live and learn. Ok. Ill go get a new clip from the bone yard on my next trip.

Thanks again Dave.
