How Does Warning Light of Roadmaster Invisibrake System Wire to Towed Vehicle

Question:

Can you tell me which wire from my Freightliner Brake Controller 2020 Fleetwood Discovery 38W I need connect to the red wires for my Invisibrake warning lights and alarm? I am passing signal from my tow vehicles RM Brake Light Switch through the center pin AUX of the 6 way on the vehicle side.

The warning light for the Invisibrake needs to connect to the stoplight switch circuit of the towed vehicle so that you know when the brakes of the vehicle are getting applied. This would not be a connection made on the Freightliner's wiring like you mentioned. I attached a diagram that shows how the monitor system wires up for you to check out as well.
