The wiring to the 5 marker lights on top of the cab is routed thru the left side A pillar. Starting at the light switch it enters thru a hole just above the left foot well fresh air vent, up the center of the left A pillar. The way to access the wiring comming up the A pillar is thru the hole that the sun visor spring/pivot slids into (remove the left sun visor) and the hole in the top of the cab for the marker lights.

This is going to be a bit of a pain getting this wiring out to repair or replace and pulled back in. I plan on tapeing a pull string onto the marker light wiring so while the wires are being pulled out there will be a string being pulled in the place of the wires. When the repairs are made I will tape the repaired wires to the pull string and hopefully pull the wires back into place.

I hope that made since.
