You can pm me as well for advice or suggestions. I am a fabricator of electrical harnesses for custom applications. I primarily use late model GM parts and update older vehicles. I would suggest to use a separate remote fuse block for all of your accessories using relays for activation, fused, etc. There are a lot of ways to build a harness for the features you want but I have several questions for you first. You really need a well thought out systematic approach and then have a detailed diagram drawn up. My questions revolve around your charging system requirements, NHRA approved controls (if need be), etc. So drop me a line-this will be fun!
