I reused the relay diagram from helping out night(hunter?), but yes, MS PAINT ALL THE WAY!
You're going to have to do a lot of work to get away from relays. I count over 30 of them in my car, stock.
I just put another battery in the car. For me the tank is really that- If i want to leave my car comp on while I go into the grocery store and not have to worry about a dead battery, I can. Also, no more of this "ooh ooh look at me I can't survive crank" bull ****
