at a loss. i have replaced the fuses multiple times, have replaced the in-dash controller and the relay (by the BCM). have also checked all connections for corrosion or broken wires. i cannot get the trailer brakes to work. i can adjust the trailer brake gain, but when i pinch the *****, i get nothing. and i have no juice at the trailer plug. i have juice at the relay (red wire), but with brakes activated i have no juice out at the blue wire. hoping someone else has run into this issue. also have no juice at the trailer plug battery pin.

No power to the plug means incomplete connection before the plug. Going to have to test at every test point working your way back from the plug.
