CB Radio Wiring Question

Just run the Coax through the hole where the taillight wires are then zip tie to the other wire harnesses running along the frame, up through engine bay and through firewall to the cab.

I wired power to the glove box fuses using a fuse tap.

I use the teraflex bracket by rear driver tailgate. Does require a hole in the https://www.amazon.com/dp/B006D9W2I0/?tag=wranglerorg-20

You’d need to file powder coat from the hole so there’s metal on metal contact.
Another option: Quadratec does sell a stainless steel bracket for below/above the driver's tail light. I chose that one because it's stainless steel and should be a better ground to the body.

A stainless steel antenna bracket is a MUCH BETTER way to go than powder coated steel brackets are. SS makes it far easier to provide the RF ground required by the antenna mount.
