I need to run some wires from a backrack mounted strobe into the cab. So how do you guys do it? is there a gasket in the back wall, under the cab, etc.
Searched around, but didn't see a promising spot.
it's an '06 F150 supercab. thanks

 

My 06 is a crewcab and I ran my wiring for my power tailgate lock under the cab and up through the passenger rear door sill. There was a rubber plug there. Although we have different cabs there still should be a similar plug somewhere under the cab.

 

dont know exactly where you mounting it but if its low behind the rear seats theres a rubber flap you can run it into then just run it below the carpet.

 

I wired a rear view camera on my 06 supercab. Like Blang says, there is a plug under the sill of the passenger door. I pulled the sill off and ran my wire in the same channel as the wiring harness instead of trying to feed it under the carpet. No drilling or new holes were needed.

 

there are vents i believe somewhere on the back wall that lead to the outside for preasure purposes.

 

When I installed my back-up camera, I ran it through the vent. It is far enough to the left I didn't have to run it under the carpet even. Just fished it in through the vent and to the left to the sill. Completely hidden. I ran it up the frame rail and the vent was closer than the rocker.

 

excellent, thanks for the help. I'm going to aim for the rubber vent and to the cig lighter power source on the backside of the center console. anyone know if there are two of these vents. i saw what i think you're talking about on both sides, approx. 4" tall by about 2" wide between the bed and back wall.
Also any way to get back of rear seats out in a somewhat easy way? a few tabs coming up out from the top, but they don't seem to do too much. this would make it easier to fish the wires thru I think. thanks
