Small bed storage box w/ outlet

To help out a few fellow members as I recently installed the same outlet I got from a junk yard in my 4cyl truck:
1) No, Non TRD trucks are not prewired for this.
2) There is a rubber plug to feed wiring through from the frame into the cab, look under the frame rail right under the passenger seat, it's about two inches in diameter.
3) Best spot to mount inverter is under passenger seat NOT IN ENGINE BAY (water and mud gets all over there), factory one goes under center console but space is limited so if you ahve an inverter of over 10 inches in any dimension this is not an option.

Hope this is somewhat helpful. There are some threads here on this or feel free to shoot me a PM.
