Did you recently connect a trailer to your car or truck, but the trailer lights don’t seem to light up? There are several reasons why that might be! Trailer hitches should have a plug or wiring harness where you can connect the trailer, so that brake lights, reverse lights, and turn signals light up on the trailer at the same time as your vehicle. Depending on the configuration of your vehicle and trailer, there are many possible points of failure. In this video, Andy guides you through a step by step diagnosis of the trailer wiring. In our case, the problem was missing fuses and relays. It’s also possible that corroded conductors at the plug, or corroded or broken wiring could also be a problem. The best way to find out is a step by step methodical diagnostic process!
