Hey don't shoot me, just got a simple question that needs one answer. Friend has a 91 CRX DX and has a 91 LS motor. Can he just use his existing harness to go from DPFI to MPFI or does he have to modify it? I used to search, but it was flooded with results and instead of going through each, I just thought I would ask. Thanks in advance for those who help.

 

yes, modified of course. or just hit up RYWIRE
