I ran a heavy 8 guage cable from the battery to a fuse and then to a fuse box that I mounted up above the driver's left leg in the area where the stock satellite receiver would have been mounted. That's the power source for a pair of relays.

From the ignition controlled cigerette lighter I ran a wire to each of the two switches. They feed a +12VDC control signal to each of the relays.

When the ignition is on +12VDC lights the switch. When the switch is turn on that voltage runs to the relay causing it to operate and closing the armature which connects the battery power up to the lights.
