Remote Batt. Disconnect

[D.B]

Just curious why you couldn't install a high amp relay and a battery with top and side post. Wire the top post neg to engine, top post pos to starter. Then the side post neg to frame and side post pos to run everything but starter. Wire key switch to trigger relay. When relay is off there is no power going to the truck except for the starter which is off the battery. Or you can wire in a toggle/rocker switch instead of the key switch. Flip the toggle/rocker on then turn the key. I have not tried it but have thought about it.
