I thought I could create load for the brake controller to see by using a headlight and paralleled it with the brake (blue) and ground (white) the light came on, the dash indicated that the trailer had been disconnected so of course no pump , did not try disconnecting the blue and attaching the light in series.

A test lamp from blue to ground is enough to fool my Prodigy controller. Maybe the factory controller is the difference.

For sure it is the difference, many comments online about it. I did find a TSB that indicates a flash to the software so will call the dealer about it.

Some trucks need a brake magnet wired into the system. Titan brakes and Kodiak sell a module that does the same thing. I remember reading that many 2015 and older trucks need it. My 2016 GMC did not

this is interesting, Im curious if the module installed on my trailer ss meant to do this but for some reason my controller isnt functioning properly (keeping in mind my neighbours truck has the same IBCM module in it and the brakes work as they should) I might try adding a 4 ohm 50 watt resister to the circuit just to see what happens. Perhaps I was close with the headlight but not enough load.
