There are plenty of threads on this sight regarding running wires through the A (front windshield support)-Pillar. They are all good and address important issues including water leakage/sealing.
However, they mostly require removing the sun visor. This is all well and good, but I needed to get my CB wired, and was unable to get the visor removed. Additionally, I was leaving for Moab the next day.
After making several unsuccessful attempts with an electrician’s fish tape running through the marker light opening (which holds the grommet), I finally (unintentionally) forced the tape through a sort of spongy impasse around the level of the dash. I then hooked the center of 20’ length of solid 4-conductor telephone cord through the end of the tape and pulled a “double length” through. I cut it from the fish tape leaving 2 lengths inside the entire run. I used one length as a draw cord to pull the CB antenna through the entire length of the channel. I left the second one in place (knotted and tucked under the running light grommet hole) for a later installation of wiring for roof lights.
While the existing A pillar wiring harness runs outside of the A-Pillar, under the garnish on the windshield side, this method runs through the A- Pillar and exits near the vehicle floor through a roughly 3” square hole under the kick plate trim. There is other wiring coming through this opening. I’m hoping this may help others trying to run wiring.
Necessity is a Mother!
