Nv4500 swap wiring

[79k20NY]

I currently have an nv4500 out of a 96 Chevy. I’m trying to figure out how to the wiring situation. I’m going from a th350 to the n4500 behind a 454 has anyone done this swap? What do I need to do for the wiring?

Following. The Tconverter just failed in my TH400. With all my driving back n forth from Kansas City MO to Panama City FL ive decided to finally do the swap. With my build im hoping to achieve 16-17mpg which I think is manageable. I just picked up a GM NV4500 from a 97'. Studying up on the swap and ill report back. I do not think there is much in the way of electrical to be done aside from the reverse light and I would assume its only an issue of splicing in the correct pigtail if memory serves. Lol but often memory is a bit fickle
