Expert Reply:
The S.H code indicates that there is a short somewhere in the brake wire after it exits the rear of the controller. Using a circuit tester check the brake wire pin on the vehicle side of the 7 way connector when the manual override switch is activated. If you are getting power there, then the short is in the trailer. If you are not getting power at the connector, try checking for output on the brake (blue) wire behind the controller. It's just going to be a process of testing the wire at various points to determine where your short is.
