i heard that an obd0 ls engine harness will plug into my crx without converting any wiring. is this true.

 

should plug in, yes...think sometimes the distributor plugs are diff on some obd0 stuff

 

If its a SI yes.

 

Wow wow hold on min. An LS engine "harness" yea it may plug in but probably not work without out modification...just use your stock harness, everything will plug in correctly to the B18 without any problems if its a SI, HF and DX will need some modification, always use your stock harness and convert it as needed, thats advise will save you many headaches down the road...

 

And IF you use the ls harness.....make sure its compatible with the years. 88 si and different.
