Typically with T-one style trailer wiring harness like the part # C56285 with issues like this fix is to just disconnect and reconnect the connectors which ensures the pins end up fully seated. Otherwise you'll need to use a circuit tester like part # PTW2993 to test for voltage on input side of box and output. If input is there but nothing on output the issue is the converter box is shorted out.
