    Sorry if this has been discussed before, but I’m having trouble finding a way to cleanly route wires to the rear bumper of the truck to install my flush mount led pods. Anyone have any pointers to run the wire from the front to the back of that truck?

    I just ran a pos and neg from the battery to the bed and went along the drivers side frame. It runs next to the gas lines for a couple of feet, then beside the gas tank, then just up and over the frame crossbars under the bed. Took about 20 feet or so of wire. I used 10 gauge due to the length, but your lights not need that much. Get a wire loom too.

    They are rough country 2” pods that came with the rear bumper. They already have a harness built. So instead of running it through the cab you just ran it down under the engine bay all the way back?

    Yes. If you are going to the battery, no reason to go through the cab. It’ll add unnecessary holes and frustration on you. I’ve run some in to the cab and it’s a pain if you go through the rubber grommet in the firewall. Just get the wire loom and plenty of zip ties.

    The switch will have wire run in to the cab though. You can try the firewall grommet or there are several other rubber plugs under the truck you can run through and fish it under the carpet. Just seal it afterwords.

    I installed a backup camera in the tailgate handle. You will need to run a fused wire from the fuse box or battery to a switch in the car. I highly recommend stashing a relay under the hood and simply using the 12v accessory/lighter + for the switch. I used the grommet on the pass side of the firewall. From the relay or pass side firewall grommet you can simply zip tie to the frame all the way back and to the bumper.

    The added benefit of the relay and using the 12v acc circuit is that it will kill the lights when you pull the key.

    Did you tie into an existing switch (i.e. cargo light), or use the one provided with the bumper?

    I used the one that came with the bumper for the time being. Switch pros definitely in the future.
