The definitive list...

@Bobzilla Thanks. I have the entire underhood wiring from the 98 3500 truck that my motor came from, fuse/relay box and all. I may have lucked into a 98 wiring schematic to help narrow down the keeps and discards on the wiring. Like you though, finding the time is most of the problem....lol.

I have done the same swap on a 79 d100, with all the factory electronics, it's not especially hard, but a lot of studying the schematic to determine what you can get rid of. One important thing is you need the PDC (underhood fuse box) as it has the relays you need for the fuel pump and ASD relay. If I can help, let me know!
