Where do you guy's run your antenna wire. I was thinking of running it through the third brake light. I would just need to notch it out and silicone it.

Ran mine down along the frame rail and in to the cab where the e-brake cable enters.

you can also run it out through the vents behind the cab if you are going to the bed. Currently i have mine running out through the weather stripping on pass side rear door. made a hol behine it and ran wire through.

Mine is run through the firewall, to the left of the steering column and behind the power panel. My antenna is installed to mirror the existing radio antenna. Pictured in My Garage.

mine is currently ran through the door sill but will be rerouted through the firewall. Antena is mounted on pass side tow mirror mount.

My antenna is mounted on the front side of the bed, (ant inside bed). The cable runs over the top of the bed, and between the bed and cab, then along the frame to the firewall. I put another hole in the firewall, with a rubber groment and to the cb. My Cb is mounted beside the ashtray and under the raido and pocket/cubby hole. Because mine is mounted to plastic, I mounted it with 4 bolts, and a strip of metal behind the plastic. Haven't have a crack yet. Mic hangs off the pocket/cubby hole on the roof behind the mirror.
