24 valve swap

[Ty75]

So I bought a 24 valve engine/trans/transfer case. I'm collecting parts for a cummins swap in my truck now. I'm trying to figure out all the wiring on a 24 valve and how to get it to work in my squarebody. I have a 1975 Gmc k20. Has anyone done a 24 valve swap personally? I would really appreciate some pointers.
I'm kinda lost with all the wires and sensors and ****. I have a parts truck so parts aren't a issue. Just need some pointers and some short cuts if possible.

Generally it is simple, all that donnor harness is going to care about is power and ground. And it will have outputs for your gauges and lift pump. You might need to add fuseblock and relay block to provide power to it.
