Hey guys, does anybody have pictures or tips on where they have mounted CB radios? And how you have wired them in. Thanks!

Sorry guys, 1999 1500 silverado ext cab z71. I've found a spot for my radio, now im just trying to figure out where to route the coax cable. My antenna is mounted on the driver side with an underhood mount. I also need to figure out where to wire.

I routed my co-axxial cable through the same grommet that brings the parking cable into the passenger compartment. This was a little tricky and I used a length of RG-174 cable with SMA connectors at the radio end, and an qualilty antenna base at the other end that accepted an antenna with a PL259 base. This was for my amateur radio dual band radio with 50W output; RG174 cable is very thin, and the SMA connectors are also quite small.
I took an old aluminum tent pole, made two axial cuts at one end one (90 degrees to each other) that were about 1.5" long. I then bent these in to make a point. I used this tent pole as a sort of needle, and pushed it through the grommet opening, halfway into the passenger compartment. I then pushed the RG174 cable into the "needle" (the SMA connectors fit into the tent pole). I pulled the "needle" into the passenger compartment from inside, and it brought the cable with it.
SMA to PL259 and SMA to SO-239 adapters are easy to find. This allowed me to make the connection to the radio.
Since I have a Yukon, I had to fabricate the antenna bracket (they're available for Silverado/Tahoe, but not for Sierra/Yukon!!!). The second photo shows the thinness of RG-174 cable.
[EDIT on 3/3] - Forgot to comment on wiring: I used the same method (Tent-peg "needle") to bring #12AWG wires from the power block under the hood to the radio. I can run up to 50W on the 144 MHz band, meaning 100W+ input into the radio. For a (legal) CB, your maximum current is around 2A, so should be able to have good results with #16AWG wires, which would be easier to run. In the past, when I was running a CB, I tapped into one of the circuits under the dash with good results.
Good luck!!
