i am having trouble chasing down the problem in my brake lights on my 63 c10. i am no electrical wiz. i have juice at the fuse box, at the switch under the pedal and it works, juice from the white wire going to the steering colmn harness. that's it where does it go from there? i don't have any at the plug going out the firewall to wires going to rear. i an also a little sketchy on how they work in general. i always thought the brakes were the brown wire along with the tail lights, the green was one turn, yellow was another. how is the brake brighter and how does this really work. i have several other electrical questions but will stick to one for now. thanks, hr
