hi every one i have a few quick questions ok so to do a mpfi swap onto a d15b2 do i need a jumper harness or just the d16a6 harness? do i need the d15b2 ecu or will mine work and is there anything else i need to watch out for while doing the swap

 

you have more reading to do.

the point of mpfi is adding 2 injectors.

replaces stock ecu, distributor, intake manifold. wiring is adjusted accordingly to allow for these units. 2 more injectors, 1 more sensor internally in the distributor.
