I'm surprised no one is using remote switches. I installed a switch for my Rigid light bar in the card holder, but since it is such a pain in the butt to wire switches in the Canyon's cab, I went with a remote switch for an outlet in the bed. I ran an 8 gauge wire from the battery directly to a 20 amp remote-controlled switch in the bed that powers an outlet for the fridge. No wiring in the cab. The fridge is powered from either an ArkPak containing an Odyssey Deep-Cycle battery, or from the new outlet...which can also charge the ArkPak at the same time. The switch is controlled by a 2-button remote. When the fridge is plugged into the outlet, I can turn it on or off from inside the cab...and can also monitor the fridge temp from the cab. The switch is the little black box in the upper left of the photo below.
