I need to find a wiring harness to swap a '91 ford 7.3L diesel to '94 ford 7.3L. If there is anything else you could help with on this swap it would be appreciated. thank you

Is the 94 the IDI or the powerstroke? Being a mid year split it can go either way, If it's the stroke there is a guy on OB that has done it and wishes he hadn't, he had to swap the entire wiring harness and computers. What trans are you using?

I believe it is a powerstroke. The motor had an auto tranny and out truck has a manual. I'm pretty sure we have to swap the whole harness.

I am not sure but I thought the onley way you coud get a powerstroke in 94 was with a manual the autos had a turboed 7.3 idi

If it is a powerstroke you might try this guy http://www.thedieselgarage.com/forums/showthread.php?t=29651
