That’s pretty funny. I completely understand.

No, 1994/95 F150/Bronco MAF trucks were OBD-I.
Is the trans harness different between OBD-I and OBD-II? Could he just source a correct OBD-II E4OD ECU and then use his existing trans harness from the donor truck?

To install the output shaft you have to take EVERYTHING out of the transmission. Install the 4x4 shaft and put the transmission back together again.

I rebuilt that 4R70W so taking it apart is no problem to for me. But i dont have the 4x4 shaft or extension housing for a 4R70W and the E4OD from the donor has been recently rebuilt also so thats why I wanted to use it

I've been considering a 4wd conversion for my 94 for a while. Actually thought about it on my previous 95. Both are MAF with 4R70W. I believe for pre 96 this is the only configuration that got the mass air setup. I now remember reading a post someone made years ago with a silver F150 with 4wd and a 4R70W, so they may not be very common but were produced. I agree that converting everything to and OBDII E40D configuration would be much more difficult than just getting the appropriate 4R70W components.

As you know, Ty, I will be converting my son's '95 F150 to 4x4 this summer. His truck is also MAF, OBD-I, and 4R70W. However, the donor truck is an '89 with AOD so I will just treat this as a conversion to manual trans as far as the ECU is concerned.

Sounds reasonable to me. I don't see why that wouldn't work.
