This weekend I intend to wire up my rear facing trailer lights. I haven't been under the truck to look, but does anyone have any tips on getting the wires for the switch into the cab? Are there any grommets or easy places to run the wires?

Thanks

Passenger side behind the glove box, I believe, there is a grommet for running wires into the cab. Probably easier to get to from the engine bay.

Also, grommet in front passenger floor. Useful if you want to hook into the fuse panel in the passenger kick panel.

 

If you look at the large rubber grommet on the passenger side that has the factory wires going though it look to the right and a little lower then that one. Helps to be on a stool with a flashlight looking for it. There is a 1.5 inch grommet that you can pull out easy by hand and can also see very easy running a wire though once you drop the glovebox door. Took me maybe 2 minutes to get my LED bar wiring though it.

 

Excellent info. Exactly what I was looking for. Thanks for saving me some time.

How about an accessory power wire to tap into to power the relay for the lights? Anything safe and easy to access?
