All this talk of switches, isolators, solenoids, etc. makes me sick. I wired mine in parallel and put a disconnect on it. When I leave the truck sit, I'll disconnect it. When I go to drive it, I'll hook it up and go! Extra power for the winch that is on the way when it's hooked up, and like it's not even there when I disconnect it. I used #2 welding cable to hook it up and a stock battery tray from a diesel that I scrounged from the junkyard. All in all, a good mod. /forums/images/graemlins/smile.gif Made me some new battery hold downs too, don't know what happened to the old one but I was using a rachet strap as the last universal hold down failed to hold the battery securely when I rolled my truck over. I was working with the sawzall on the rear fenders and I got a little bit carried away. Oh well...at least it'll still clear the 38s when I take the body lift off. My truck is hacked almost as much as Steve's now. /forums/images/graemlins/smile.gif A little too much for a DD, but since my truck is a weekend driver/trail rig and I'm going to be swapping bodies soon it's fine. Less place for mud to hide and rust it out too.
