Montana 3970: front brakes appear to be working rear brakes do not. My truck (2017 Ram 3500) shows ‘trailer not connected’ on the dash.
I’ve tried to isolate by pulling the breakaway cord and that’s how I know both fronts engage whereas both rear do not. I’ve found the Blue wire where it feeds the rear wheels and a test light shows pulsing power when the brakes are on.
I think it may be the butt connectors (either power feed or ground) going into the left rear prior to feeding through the axle to the right side!!

Any help to diagnose further would be much appreciated.
