91 7.3 idi engine swap
Doing a engine swap a 91 7.3 idi into a 94. 94 has a 460 with e4od. 7.3 has E4od as well. My question is will the engine wiring/harness b compatible with 94 idi dash cluster or will I have to use 91 dash cluster?

Nothing will be compatible. You'll have to use every single bit of wiring from the donor truck if you want the E4OD to shift.
Your best course of action would be to find a '92-'93 IDI transmission computer if you want to alter the least amount of wires.

I think your best bet would be to source a 92-94 IDI truck for the wiring and such. Only the engine and trans from the 91 are useable here, the electronics need to come from 92-94 IDI truck.
