What's easier?
 

Hey guys--I have an '88 CRX Si I want to swap the engine/tranny/ecu from into my 91 Dx, is it easier to de-pin the existing wiring harness, or swap out the entire CRX Si one? It seems like the best thing to do, although it would take longer, is to swap the whole harnss. Also, I was gonna swap out the gauge cluster too, will it work without rewiring the harness? Thanks

So do you want to swap the si motor in or out? sorry i am confused...

What's easier
 

Yeah, sorry---I have an 88 CRX Si parts car that I want to take the motor, tranny, ecu, etc., out of and put into my 91 DX hatch. The trouble is the DX is DPFI, the Si is MPFI, so I was thinking I can swap out the entire harness, even if it's a little more work, rather than rewiring my existing harness for the MPFI swap. I didn't know if that was even possible, or if I'd just be wasting my time.

Swap the harness it would the better of the two choices.
