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.

Good innovation Tower & sounds like MOAB was a blast. On the visor they are VERY difficult to remove even when you know how (not one of GM's better inventions). I avoid it by working from the front of the headliner at the windshield. Just pull down slightly & start the wire and it will pull back behind the headliner with no problem. This is if your fishing wire from the overhead console to the Apillar.

Re: Wiring the A-Pillar -- CB, Lights, etc.
 

The sun visor removal is ridiculous. I am installing factory brush guard lights and the instructions simply say "remove sun visor as shown" and it shows a ribbon type action. Amazing. I spent an hour and still didn?t get it removed. I will try the above methods tomorrow!

Hey Tower!!!!!!!

How are You Bud. Both of us have not been around much. I have been back for a few months but not consistantly. Depends on how sick i feel each day.

Did you by chance take pic of the extra wiring runner route? I have read Your discription and I'm not well the end of this week and I cannot make it register in my head as i normally do. I have had all that stuff off so much I should be able to visualize it but, drawing a blank.

No pics no biggie thought i would ask as You are usually good about pics with detail stuff.
