I just bought a 91 si civic hatch and the harness in the cabin is cut up beyond belief and I need to know if I have to have a si harness or will a different one work thank you in advance

 

as far as i know the SI harness is unique to the SI chassis. so im gonna assume u will need a new SI harness..

i do know that the DX harness is completly different than the SI harness and the two do not interchange.

 

ok thanks anyone else have an opinion on this

free bump

 

im running a DX dashboard harness (at least it was a DX crx i pulled it from) an the rest of my harness is an SI. no problems here.

 

the dash board harnesses will work ( i did the same thing) but the cabin/engine harnesses will not mix and match

 

You will want an Si harness to match the engine harness,if you were to use a Dx harness it would not match the engine plugs.

 

correct ^. dpfi harness lacks the wiring for the extra dizzy sensor and the extra 2 injectors. you must use an Si harness.
