I just did this in reverse, I put a 1994 E4OD into a 1996 Bronco. You can source the correct plug that connects at the transmission on eBay. The plugs tend to melt, especially if the heat shield is missing like it was on mine, so replacements are readily available.

I bought the 94 plug and then connected it to the 96 harness. The wire colors and circuits are all the same. I got the pinouts for 94 and 96 and compared them. All you have to do is solder the wires on the 96 plug to your 94 wires, the colors are the same.

The transmission does not care about OBD1 vs OBD2.

He would not need to run a new wire for the moving of the diodes. I do not understand why you would ask that question.

Plug

Subford, That "C1049" plug you show , for the 4r70w trans is what I have. I don't understand why. The door tag shows "E" , for a e40d trans. But, it is what it is. I have to deal with it. If you look at the wiring and color codes, all match EXCEPT, the wire for the "coast clutch solenoid" . That's the only wire that I don't know what to do with. Unless I run a single wire straight to the pcm. Me and Jackietreehorn feel theres no other way to make it work. What do you think.??
ALSO Subford, would you happen to have one of those BIG schematics for a 1994 with the 4r70w trans, just for the hell of it , I would like to compare.
