    since you have access to it, just swap the entire cabin and engine harness from the si into your dx.

    lol found this thread right after i made the same one : p

    im just starting a b18a1 swap into a 1990 dx but i dont have any si wiring, im thinking it would be less complicated wiring wise to install the body harness aswell and the engine harness from the integra which would hopefully eliminate re pinning of the ecu contacts, the only wiring i forsee as of now is lighting sockets and heater fan connectors... thoughts anyone

    i guess the main problem ill have by swapin the dash is the rest of the harness plugin in the dash meaning goin to the back of the car and goin to the head lights.. im surprised no one has done this swap before...

    The dpfi to mpfi wiring is pretty easy, there are tons of good write-ups floating around.
