We can all sleep well tonight. I took a switch out of another steering column I had laying around and installed it into the Dart. Everything is now working as planned including the left brake light. I tested the one I took out of the Dart and found no reason why it won't work properly. All wires have continuity and all connections tested properly. Thanks for all the input. It proves 9 heads are better than one old one. Now onto hopefully the last electrical issue, the instrument panel lights won't work. Picked up a new light switch today, will start on that one tomorrow.
