hi all, my question is very simple: i have a donor 91 integra LS and i'm swapping the engine/tranny into a 91 CRX DX; i have already put the engine and tranny in the CRX but now im a little confused, i've read so much about this swap but no one has ever mentioned about using both engine and dash wire harnesses. is this the way to go if you have a complete donor car? do i still need to do the DPFI to MPFI conversion? thanks for any info.
