Troubleshooting Curt Harness With Shorted Out Converter Box

Question:

I have a troubleshooting question. We purchased a used 2019 Jeep Compass with a Curt trailer light kit. The fuse was blown. When I replaced the fused the right side taillight came on with no lights turned on. My question is itbit possible the converter box has shorted and is allowing power from the battery to back feed to the vehicle taillight?

With the fuse blowing on your 2019 Jeep Compass while using The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56369, it is very possible that the converter box has shorted out and is allowing power from the battery to back feed to the vehicle taillight. It could also be a loose wire on the vehicle side causing it to be constantly on you could check each connection using The Hook Probe Circuit Tester Kit # PTW2993.

Using the circuit tester will find electrical shorts and will allow you to see if you have any loose wires on the vehicle side. It could also be that the whole harness gave out. The normal vehicle harness typically lasts for only a couple of years. If the wiring is completely bad you can just repurchase The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56369.

I attached an installation video link below.
