    Default How to route CB cable out of cab?

    My CB cable which is currently running out under the door gasket on my extended 2003 Sierra isn't cutting it. I am limited by cable length and can not run it out through the firewall. Is there any other easy way to get my antenna to the back of my cab with out cutting a hole?

    have u looked under your floor carpet, driver side. there should be a grommet in the floor where the parking brake wire goes through the cab. i have most of my power/other wires run throught there. at least thats how it is in my 05 silverado

    Yep that drain plug in the driver's side floor is where I ran all of my off-road wiring also, no cutting and it's about 3" in diameter.

    Thank you. I decided to roll under the truck last night and look to see what I could find. I discovered the e-brake cable and ran my CB cable through with it. The sealant I put over the cbales is dry now and should serve me well. Thanks!

    Now my next project is to look for some captains chairs!
