My car is a 1991 Honda CRX DX. My engine wiring harness is hacked up pretty good. I plan on replacing the harness, because i plan on swapping a GSR or a B18C ITR motor. What wiring harness would i need? Or what could i swap in and have to do the least wiring work on?

 

the crx wiring harness unless you want to cut up the newer one off the engine your getting

 

you want the stock harness that came with your car, and then you'll need to convert it to mpfi. either that or you can send rywire your harness and the harness from the engine you're getting, and they will send you back one harness thats been converted to mpfi, and will attach to your new engine, with instuctions on how to hook everything up.
