Custom trailer wiring and brake controllers
Safe towing depends on having wiring set up correctly from the start. Whether you need a single bulb swapped or a full wiring system built, every job is designed for your trailer’s unique needs.
Larger trailers often require brake controllers or full power brake systems, all fitted and calibrated for safe, reliable braking.
No two trailers are exactly the same, so your wiring is customised to your setup. From adding an extra controller to designing a ground-up fitout, you get a trailer that tows smoothly and wiring that simply does the job.
