[67C10Step]

Ha, ha! I am doing the same thing and just found this very switch over the weekend. I got my tail lights working, dome light working, and backup lights (if they were installed) working. Now trying to sort stop lights and turn signals. Power all the way to the semicircular connection in the column so that is coming apart next as it appears it might have a few issues.

It's odd, when I hit the brake pedal the left front turn signal comes on. Have not checked to see if power is going to the rear as well.
