Roof top Running lights electrical feed

[PbFut]

Well, that was the biggest challenge this truck has given me. Except for a quick lunch break, I spent all day. The holes in the A pillar proved too much for me. I spent a good 2 hours each side attempting to find the hole. Felt like I was in high school again. Never did find the hole. Even with the great pic Doc provided in his link to a different post. I know I was in the correct area over the seem from the visor hole. I never felt my feeler wire hit the hole.
I was not confident with the floss trick posted above but it proved to be the necessary step though I had to snake to the B Pillar. The vacuum was not enough to pull the floss from the Sun Visor hole. I had to rig up a smaller vacuum tube (heater hose) to get high in the B pillar. I then used a continuous blast of compressed air shot into the visor hole pulling the dental floss and directing to the area of the vacuum. Once the floss was pulling on it's own I knew it was in the vacuum tube. I then attached the speedo cable to the floss at the B Pillar. I needed to gently pull the floss to guide the speedo cable tip past the roof seem and pushing lightly on the speedo cable. Once the speedo cable was the full length and protruding out the visor hole and an end left at the B pillar hole by the gas filler neck, I was able to attach the wire to the speedo cable and pull into its final position. A second fish from the visor hole up to the running light hole completes the daisy chain. I'll hook up and complete the light mounts tomorrow. A beer is setting next to me to celebrate completion of a task that should have taken no more than 30 minutes and burned up most of 3 days. I was not going to let this wire beat me. Thank you for the tips. Proved to be very helpfull.
