I'm installing a new amber light on my 2013 F250 signal cab and was wondering where most people run the wires into the cab. It has a magnetic mount and I didn't want to put a hole in the roof. I have a cap on the truck and I also don't have a sliding rear window. This will not be a temp. install. Has anyone ever put the wires in through a hole in the 3rd brake light? Any help would be great. Thanks in advance.

 

Mine were put through the highlamp brake light, the center light that is on top of the rear window glass.

I have since disconnected it.

i run the wire through a small hole drilled in the floor under the rear seat, put a grommet in the hole, then seal the hole with silicone.
run the wire up between the box and cab.
or for a full size arrow stick i run the 12 conductor wire through a hole in the firewall treated the same way with grommet and silicone, and run the wire along the frame, then up between the cab and box.

 

Me too. I also put weather pack connectors under the the cab. That way if down the road you need to remove it you don't have to remove the whole wire.
