There are 3 power ports in the truck. Front one is by the front passenger's left leg on the center console. The second row one is on the back side of the center console, left of the rear radio and climate controls. The third one is on the passenger rear quarter panel, accessible when you raise the lift gate.
There is also the cigarette lighter in the pop out compartment of the center console, although you're technically not supposed to use that to power devices.
To get to the front plug, remove the upper part of the center console. Right where the pop out ashtray/cig lighter, there is a rubber mat. Lift that, and there should be a 7mm (from memory) bolt. Take that out, open the center console lid, and lift up. I usually just grab around the cup holder area and pull up. Aside from the bolt, the upper center console is held in by clips.
