Hey peeps, I'm RT and I have an '83 MC restomod that I have been working on since 2020. This is my first (and last) restomod and I'm at the point where everyone seems to struggle and that's the wiring harnesses. I have done a ton of research and purchased a custom Engine Harness through BP automotive. After many months of research and reading online and reaching out to aftermarket companies, I purchased a universal wiring harness for inside the car through American Autowire. I have an WS6 LS1, 4L65e, complete Vintage air kit, Autometer gauge cluster, and everything is new but the wiring is intimidating but I feel like I'm a pretty smart guy so I should be able to figure out this wiring thing. All the old wiring is out so it should be simple to get started, but I don't even know where to start and I don't want to make a mistake along the way. Any advice is welcome. Thanks
