CB install help

I just purchased a BAMF CB mount for the back passenger side of the truck above the rear tail light. I want to run the CB cable to the cab of the truck. Is there a firewall hole in the back between the bed and cab or underneath somewhere. I have an 05 DCSB. Any pictures of others who have done this would be appreciated. Thank you TW.

 

There is a wire loom under the driver seat that you can put the antenna cable through. Look underneath your truck and you'll see it. You can run the cable from the CB through this hole along the frame rail and behind the passenger side taillight.

Thanks this is a great start. 18 feet should be long enough correct?
