Trailer electrical
Trailer Wiring, Lighting & Connector Service
We diagnose, repair, and install common trailer electrical connections for personal, work, and fleet towing setups through our Tyler shop.
Trailer lights and connectors
Service can include 4-way and 7-way connector installation or repair, damaged plugs and terminals, poor grounds, and tail, stop, turn-signal, marker, and related trailer-lighting circuit faults.
Test the tow vehicle and trailer
A lighting or connector problem may be on the tow vehicle, the trailer, or both. When the fault crosses the connection, bring both so power, ground, connector pin operation, and the affected circuit can be checked together.
Brake and auxiliary wiring
Trailer brake output, auxiliary power, and related wiring may involve the connector, tow-vehicle wiring, brake controller, or trailer circuit. We identify the affected side before defining the repair.
