If you are leaving the guns hooked up all the time, why not leave the led power cable plugged in to the gun cable. Then you can just splice open the power to the led stands and drop in a cheap switch. You could extend the switch with any wire to wherever you want on your cab. That would probably be the easiest method for powering it up. After all, there isn't alot to the led stands, just some resistors, leds, wires, and there might have been a cap in there too.
