I have a 2000 K2500, love the 454 that it has but recently found myself working on it a lot more. So i did some digging and found that an 8.1 will fit in the exact spot. Well, $800 and a few hours later i got a 2001 K2500 Suburban with an 8.1. Now, I can handle the physical part of swapping it, I need help with the wiring part. Any and all help is appreciated.
