my car is running a b16, had a harness that was all cut up and nasty. so i went and picked up a si harness out of a ef, now all my plugs match but the one buy the resistor box, my new harness is small has has 8 little prongs. and my old one is teh big 11 prong (ithink) what is needed to swap this? i need to know asap! also i think my car was dual port before? is this why..

 

si harness will not work on dpfi vehicle.

you need to convert another dpfi harness to mpfi.

 

i dont know if my car was actually a dual point, thats just what i am guessing. i just got it.
