Trailer wiring problems are common in Iowa -- corrosion, broken grounds, and bad connectors are constant issues for anyone who tows regularly. We can inspect, repair, or install a new wiring harness and get your lights working correctly before you head out.
Gus Automotive inspects, repairs, and installs trailer wiring on tow vehicles and trailers. If your trailer lights are not working right -- one turn signal out, brake lights not functioning, or an intermittent connection that only fails on the road -- bring the tow vehicle and trailer in together so We can trace the problem from plug to load.
Trailer wiring problems have multiple possible causes. The issue could be in the vehicle's trailer connector, in the trailer's wiring harness, at a corroded connection point, or at a ground that has lost its contact. Testing systematically from the vehicle side to the trailer side is the fastest way to find the fault without replacing parts that are not actually bad.
Once the fault is found, Ryan repairs the wiring properly rather than wrapping a splice in tape and hoping it holds. Trailer wiring runs in a wet and exposed environment, so connections need to be sealed and protected to last. Corroded connectors are replaced rather than cleaned and put back.
If your vehicle does not have a trailer connector installed or the existing harness is beyond repair, We can install a new wiring harness. Most modern vehicles have a plug-and-play T-harness that connects to the vehicle's existing wiring without cutting any factory wires. Older vehicles may require a more involved installation, but the result is a clean, correctly wired connection.
Vehicles equipped with electric trailer brake controllers require a proper connection between the vehicle's brake signal and the controller, and then from the controller out to the trailer's brake magnets. If the trailer brakes are not engaging or the controller is showing a fault, We can test the full circuit from the controller output through the 7-pin connection and verify the trailer brakes are receiving the signal correctly.
In the Stuart area, trailer wiring problems come up regularly among farmers, campers, and equipment haulers. The most common calls are:
Farmers haul grain, equipment, and livestock. Families pull campers and boats. Contractors tow work trailers. All of that means a lot of trailer connectors spending time plugged in, unplugged, exposed to moisture and road salt, and generally working harder than the manufacturer's testing cycle imagined. Trailer wiring is a regular service here, not an unusual one.
