Trailer Wiring & Electrical Repair FAQs
My trailer lights don't work. Can you fix them?
Yes. We run a full wiring diagnosis to find the bad ground, broken wire, corroded plug or failed light, then repair it flat-rate. Most light and plug fixes are same-day.
Do you replace 7-way plugs and junction boxes?
We replace 7-way plug heads, complete 7-way harnesses, junction boxes and breakaway boxes, on all towable trailer types.
Can you completely rewire an old trailer?
We do full rewires, under and over 20 feet, replacing the harness, lights, plug and grounds so everything works reliably.
