i was an idiot and didn't take pics when i put this in but here are a few to give you a better idea of how to get the cable run
run the cable from the CB (assuming center console mounting) under the carpet behind the pedals
now remove the trim piece next to the dead pedal location and door sill trim piece and the door sill piece by the passenger door
and run the cable under these trim pieces
continue routing the under the side trim pieces all the way back to the rear door. i was able to just push the cable under the trim pieces in the back cargo area
remove the rear door sill trim piece. i don't have a pic of the rubber piece but directly between the door sill piece and the cargo area d ring (under the carpet) there was
a black plastic piece that i was able to cut and rout the cable to the underside of the vehicle
once the cable is under the vehicle it is easy to feed up between the bumper and the body to the antenna mount
if this is confusing or you have questions let me know.
also, with 18 ft of cable i had very little slack left at the end of the cable run so the 90 connector at the antenna was a savior.
