Hello! Glad you joined!
Where's home? I ask because we have a member's map (Bullnose Forum/Member's Map in the menu) and we could add you if we had a town or zip. As for the '96 OBD-II, Bill/85lebaront2 has already done that, and I'm in the process of doing it for both Big Blue and Dad's truck. So we do have some experience and can help. Now, back to your projects thread....

Thanks for the tips Gary. I will be doing alot of reading before I make the swap. Right now I have a homemade breather taking care of the oil puking and plan on driving it this way until the Explorer is ready to be harvested or it explodes... whatever comes first. It currently has a 6 misfire. I have plugs, wires and coil packs in the mail. Compression was good and the injector was firing per my stethoscope.
 As for the harness, I have done an 86 Bronco II to 91 Explorer swap before. I plan on doing it similar. I will take the 96 harness and trim out everything I dont need like lights, ABS, cruise etc and make it an engine/tranny harness. No need to rewire headlights or any other stuff. Then have just the few wires from the dash and stuff connected up as needed. But again... plenty of reading. There is also another Gary. Gary the EFI guy that does alot of 96 OBD2 to old Bronco swaps. He also does stripped harnesses for those.

I agree there's no reason to change out the Bullnose wiring that is working. Just interface the EFI system to it. Like the fuel pump connection, which the EEC wants to control and know that it worked. And it would help for the EEC to know when the brakes are on so connect Brake On/Off (BOO) to the Bullnose brake circuit.
But in my case, and I suspect yours because of the Explorer's serpentine system, there was the swap to the 3G alternator. That required some changes to the wiring on the passenger's side to accommodate a megafuse, take out the ammeter's shunt, install a relay for the volt meter, etc. And that was made easier by using a mid-90's F-Series PDB with megafuse. However, the later model battery tray got awfully close to the starter relay, so why not use a relay in the PDB to bring in the PMGR starter? And, put the headlight relays in there? Oh, and why not use the remaining relay to power the blower motor? Then there's the driver's side PDB that came with the '96 wiring harness for the EEC-V system. I'm going to do like you said you'll do and strip out everything that isn't needed, like I did for the other PDB. That will slim down the wire bundles dramatically since the lights, HVAC, and many other things are currently in there. In the immortal words of Paul Simon, "Say, ain't we walking down the same street together. On the very same day?”
