Default wiring a dpfi to mpfi help.

i have a b18a ls motor. and the distrubitor connector is different and how would i change it. and the other wiring conversion should be the same as the zc conversions right? like extending the tps sensor wires. and other stuff like that.


any one have pics of their conversion please post some. THNAK YOU

for the distributor wiring, get an si connector or if you have the ls harness you can use the plug off that. instead of cutting and attaching the wires back together you can de-pin them from the dx connector and re-pin them into the si connector. you will notice that the LS distributor has 2 more wires than your dx harness has. The 2 extra wires for the plug will come from your ecu when you do the DPFI-MPFI swap. hope that helped...any more questions, just ask away.

Search for DPFI-MPFI Guides and HOW TO's and it will tell you the exact pins and what else to do for the swap.
