Trailer Wiring and Connectors

There is nothing more aggravating then getting the boat & trailer hooked up, to head out to your favorite water destination for the day and quickly realizing that your trailer lights are not working or are flickering on & off. To avoid these kinds of electrical issues then take the time to ensure that your Trailer Wiring and Connections are in good working order. Frequently trailer wiring issues are the result of frayed wire or simply poor connections. To prevent these issues from occurring then look to replace, when necessary, a connector or completely re-wire your Boat Trailer.
