dude just start over. if you post up all your gauges, accessories, bilge pump, etc we can make you a wiring diagram and simplify eveeerrything. more importantly it will be safe and reliable.
That'd be sweet, I've been looking on line and can't find my set up. It has some small random additions that I can't find. And it's super shitty because I have no real place to work on it, I have to store it at a yard. Because the rules where I live is you can't have a recreational vehicle or trailer visible from the street or on the street over night. And working at the yard is possible but it's hard and not real close to my house.
So the harness build was more what I was leaning towards. Able to take all the dimensions and build it, then able to install it in a day.
