There is a hole in the cab on the passenger side in the lower back corner towards the bed. Peel back the upholstery just a bit to see it. It has a rubber grommet you must poke through or remove completely. I used this pre-existing hole to get my camera wire through.
I'm trying to keep cool and realize it's just a truck. That is paid off. I've never received so many compliments on a vehicle I've owned.
Thanks for the love. Chin up.
