I recently purchased an older 4x6 utility trailer that the owner had recently put new lights on himself. He said that they worked fine on his vehicle, but I am not sure that I really believe the guy totally. I also bought the #118376 wiring harness for my 2003 Dodge Grand Caravan. This is the first trailer Ive pulled with my van, so I am not sure which part is having the problem, and how to fix it. The passenger side seems to be working just fine. The brake, running, and turn signal lights seem to be operating as expected. However, with the passenger side, I do not get anything from the tail light. However, the side amber running light does work when the lights are on. The other part of this is I thought maybe the previous owner miswired the passenger tail light. So, I switched the wires on the tail light, and that made the turn signal work when the lights were off. However, when the lights were turned on, it stopped working again. I took a look at the troubleshooting video on your website, but I am still not sure which part is most likely affected on my lighting setup. Thanks in advance for your help!
