Finally found a nice Explorer console, but the hole in the back was driving me nuts.
This is a Cobra 480w inverter, mounted where the rear blower motor was. I just removed the end plate and extended the wires. It is set in a piece of ABS plastic bolted in place of the rear A/C control panel.
That gives me:
2 original 12v outlets
1 new 12v on the side of the console
2 110v outlets on the inverter
1 USB outlet on the inverter
