[QUOTE="vtvette, post: 1415487, member: 26504"] Hello all, I'm finishing up a 7.3 swap into a 2003 Excursion that was formerly a 6.0. Engine is from a 2002, as is the entire harnesses dash, engine bay and engine harnesses. They are from different trucks but, both are 2002. I also have a 1999 F350 parts truck. The only IDM and PCM I have are from the 1999 F350. From what I've researched the IDM should work - it seems they are all the same through all the 7.3's (although the newer ones received a bump up in voltage). My question is for the PCM - I'm assuming the 1999 PCM is not compatible with the 2002 harness? Also, are the PCM's in 7.3 trucks serialized with the VIN number to work correctly? Thanks for any help, B [/QUOTE]
