    @JdevTac I'm going to check now...

    Will the wires on driver and passenger side tuck behind the plastic trim? I'm assuming the trim gets removed and the wires tucked in there?

    That’s the best/cleanest, and most protected way to run it, yes. Pull the door sill trim panels. Pull the dead pedal and kick panel and run your wires to the rear.

    If you aren’t running to like a fuse panel or something inside the cab, the easier way is just skip going into the cab and run your wires from the engine bay straight to the bed. I run the wire inside of a protective wire loom, usually follow the OEM hard lines exiting the engine bay and joining the frame on the driver side. Stay as far away from cat converters as possible, and then run wire along frame rail, zip tying the wire as you go until you get to the bed.

    I'm not going to a fuse panel in the cab...so, I could do as you suggest and skip going through the cab...that was my first choice, but I didn't see anyplace that I was sure would be ok to run the wire/loom...

    Looks like there are three hard lines clipped into a white plastic mount...wasn't sure what those were and didn't know if it was ok to tie the loom to those...I'll see if I can get a picture....

    Looks like there is a little nipple on the large driver's side grommet for additional wiring to run through as well as the smaller grommets behind, I'm assuming, the brake booster and then a similar one on the passenger side....I'll post pics of those now...

    Does this plastic piece holding the trim just pop off...or does it have to be screwed off?

    Thanks @Cudgel I think I see a red and black wire going behind that bracket on the side wall, but I can't see where they go from there...

    @JdevTac I'll post pics of what I think you are referring to...

    Yes those small grommets are the ones I was referring to.

    for the kick panel you first must remove the door sill trim piece. Just pull upward with your hands working your way center to edges, then remove the dead pedal first with a careful but firm pull straight toward you. Then unscrew the little black retention screw, and the kick panel pops off.

    Yeah those hard lines is what I refer to. I have run my wire in tandem with them, in a nice wire loom for extra protection. On my vehicle there was an unused position on the hardline plastic clip that I put my wire in. I ran down to frame and snaked wire away from the cats. There was a hole behind the fender splash guard just before reaching the frame that I used to ziptie the wire for added retention. I actually bought a thermal sleeve for the wire run there as well but I haven’t needed it. Snaking the wire along the frame from there is easy. Ziptie it along the way to other cables. I don’t like to ziptie to hard lines. How you get the wire into the bed is then up to you.

    Thanks for the direction on the paneling. :thumbsup:

    I think I saw that unused position on the hardline plastic clip...I didn't get your message until after I routed the cable along the firewall to the grommet on the passenger side. I got as far as cutting the nub off the grommet, using a utility knife to put an "x" opening in it and fishing the cable through. I'll post pics... wire loom and zip tied up.

    I think I threw another zip tie on in the engine compartment...and also fished the wire a little better on the inside after I took those last two pics.

    Tomorrow, I'm going to go back and route the cable to the grommet under the passenger seat, down the frame rail the to wheel well/storage cubby. :fingerscrossed: Thank you for your assistance!
