Hello-
I have a '96 7.3 powerstroke that came from a manual trans F250 that I want to put in my '93 F350 manual trans that currently has the 7.3 IDI. Has anyone done this?

I have the truck that the psd came out of as a parts truck--but the prior owner cut all the wires at the engine side of the engine wiring harness to remove the engine (maybe they didn't have a 10mm socket)! I know I need the '96 engine harness and computers and I'm thinking I will need to use the '96 wiring harness all the way in to the instrument panel.

Any wiring diagrams available for these two models?

Any help is appreciated.

Since you're swapping the whole harness, you don't need the diagrams....
You do have to swap the whole under dash harness.

That's what I figured.
Any idea if the harness off an automatic will work with a manual?

Your looking at one hell'va job. Your gonna need the under hood fuse panel, the dash fuse panel with the Gem Module attached, the IDM that's in the drivers side fender, the PCM, the complete wiring harnesses, might have to change the radiator.

The 94-97 Powerstroke did not have a gem module but you will need 99% of the wiring from the under dash harness all the way to the radiator along with the associated electronic equipment along with the throttle pedal.

It has been done but there is a lot of work involved.

Lots of work--no surprise there.

One of the hardest parts is getting the dash out of the way to access the wiring harness!
Still carving the harness and related parts out of the donor parts truck.

I'm thinking of adding an intercooler as well.

The cooler is the easy part after he gets the engine swap done.

Agreed. I believe that he is going to spend more time and money than what he can pick a good PSD truck up for.

Plus all the unforeseen problems and obstacles you run into along the way.

It's not that bad man working on swapping my 93 right now

 

[oldrebuiltdodge]

I guess I'm just entirely too old for that stuff now.

That makes two of us!!

May I make that 3?:grin2:

Curious about why did someone mention swapping radiators earlier? Isn't it far more reliable cheaper and easier to pick up an aftermarket trans cooler and not use the radiator in the cooling loop? 100 bucks for the monster sized Hayden ultra cool from local pats house here plus 30 min easy install hassle free plus new clean no possible metal going into the new transmission.

Trans cooler? Might be kinda hard to find a place to connect it....

The only reason (supposedly) the radiator was mentioned was because the PSD radiator was changed mid-year '95 from the old-school overflow style with a radiator cap (same as what an IDI would have) to a reservoir style with no radiator cap with a pressurized degas bottle. The radiator hoses changed at that time, and the hose fittings from the water pump might have as well. So since the donor engine is from a '96 truck, which had a degas type cooling system, the hoses from the IDI radiator in the project truck might not fit it.

I stuck an IDI radiator in a '96. If I recall, the lower hose fit. but for the upper I had to use a universal flex hose. Don't remember the length though.
