When I was moving the wires the light brighten up once while moving wires above the column the next time it was about the fuse block. I did inspect the harness but like you said could be the connections. Also I unplugged the column harness and had nothing while the brake pedal was down. The power did go through the brake light switch. 300 bucks I can get a new under the dash harness and turn signal switch
