How Does Demco Coachlink Get Wired To Air Force One Braking System?

Question:

I installed the Towed Car Conversion Kit - Demco SBS Stay-IN-Play DUO to Air Force One Supplemental Braking System ITEM # SM99233 on my 2021 Chevrolet Colorado. I also purchased the Demco SBS Wireless Coachlink for Supplemental Braking Systems - Braking Indicator System ITEM # SM99945 How does this stop light switch connect to Coachlink indicator?

Expert Reply:

The Coachlink # SM99945 you purchased has two wires, a black that gets connected to ground, and a red wire that needs to get connected to the cold side of the stop light switch that only gets power when your brake pedal is pressed however since you converted your system to the Air Force One you'll connect it to the reed switch.

I went ahead and included a cutout to show you how it will get wired up depending on if you have a 2 or 3 wire reed switch.
