Mark you have asked the million dollar question. It is my intention to use the explorer ecu with the harness that came with the 98 v-6 I started with. According to the ecu pinouts they are almost the same except for some things that will not be in use, ie emissions. I also intend to use the injector harness for the V-6 if I can add the other injectors. I don't know but that is the plan, I think that means OBDI and I'll let ya'll know if it works. Or maybe it will be an epic failure build thread.
I hope not,
Mika
