So I picked up another crx its a 90 si shell not too bad..I was lookin through the stuff I got with it, I was told the harness was a si harness but turned out to be a Hf harness.....does anyone know if it would work with my under dash harness cause I been reading and a lot of people say it wont .

 

HF and si are not a direct swap. The wiring between both models is slightly different. If I recall. Correctly the ignition module, injector wiring and egr are the differences. Si does not have an egr where as the HF did

 

Is there a way to make the Hf harness work instead of having to buy a si harness.??.

 

Take it apart, and rewire it to match an si harness.

 

Do u know where I can get a wiering diagram for an si.?.
