Ok, so I've got my old 79 Bronco out in the shop just waiting for some TLC, and as of tonight I've worked out a deal to aquire a (reasonably) low mile 92 model IDI!!!!!
I've done plenty of engine swaps, but never a conversion of this order, so I'll be firing off a lot questions to you guys.....especially after I pick the motor up in July...but I also have a few now. For example:
Are the IDI motor mounts conventionally bolted to the frame, or are they cradled in the crossmember like the Powerstroke? If they are in the crossmember, is it a bolt in piece that I can get from the donor truck at the same time?
What wiring do I need to make the IDI run. Will I need the whole harness from the donor truck, or is at simple as supply power to the starter and it's good to go? Same question for the glow plugs. Do I need a controller for them, or can I just put them on a switch?
Will my current C6 (351M-400/460 bolt pattern) bolt to the IDI, or will I need to source a tranmission too?
I already plan on running new diesel rated supply and return lines, but what about the tank itself, and special prep work necessary there?
That's just a few off the top of my head.....I'm sure I'll have many, many more in the fall/winter when I actually can start building it.

i have just completed a swap on the '79 in the pics.and everything is still fresh in my mind.let me get a list together and some mesurements and draw a wireing diagram.

one wire powers the ip fuel shutoff and the high idle solonoid and turns on the glow plug controller.i will go out tomorrow and see what color the wire is.that i hooked to the coil wire that is powered by the keyswitch.the two fat wires go to the hot side of the starter solonoid on the fender.from the fender solonoid i ran a wire from the starter side to the small terminal on the starter.the big one goes directley to the batterys

the frame perches in the bronc gotta go.they are bolted to the frame,easy to remove.you can take the mount outof the donor truck and use them to fab the ones in the bronco.

Red wire with green stripe powers the fuel shut off solenoid.
Red green wire goes to a red wire yellow stripe in the 92 harness.
Your coil wire would hook to that one.
The starter relay wiring would kinda stay the same, the wire that leaves the fender mounted relay goes down to the starter mounted solenoid as a trip wire.
The big battery cable on the diesel starter goes directly to the positive post of the battery on both batteries.
Glow plugs, the 92 used the new style controller, so all you need to do is get battery power to the battery terminal of the glow plug controller/relay.
If yoiu want manual glow plugs, that is easy as well.
The bottom piece of the motor mount sits on a pad on the cross member, should be easy to fab with enough beer.
The tranny has to be a diesel tranny, the bolt pattern for a 460 is close, but not close enough.
If I remember right, only two out of six bolts lines up right.

Is that really all there is to it? Hook up four wires and crank it up!!!! That's awesome.

Hmmmmm. Will a 205 transfer case,which he has, bolt up to a c6 out of an 80's model 4x4 diesel that would have had a different case? I am not up on these automatics.
Or a t18 and convert to a manual truck. Clutch leakage parts for that shouldn't be hard to find. I have two sets myself.

My wife has three of her own.
I probably won't convert to a manual. I'm pretty sure all the Ford mounted T-cases have the same mount pattern....the only issue would be the size and spline count of the output shaft. I'm definitely keeping the 205. I'll divorce mount it if I have to, but there's not much length under a Bronco, so hopefully I won't have to.
What about the electronic four speed autos.....how are they controlled in the IDI trucks??

David85 has a name of a unit that lets you set the shift points.
C6, E4OD, T 19 and ZF 5 in the IDI trucks all used either a 1345 or 1356 Borg Warner transfer case.
If I remember right 87 and back had the 1345, 88 and up had the 1356.
