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.
