Pin functions follow the common Australian standard. Older or custom trailers can differ — we always test before we terminate.

Best Suited To

  • Caravans
  • Horse floats
  • Off-road campers with battery systems
  • Trailers running a 12V fridge

Plug Conversions

Changed tow vehicles and the plug no longer matches? We rewire trailer plugs and vehicle sockets properly — no adaptor stacks, no guesswork, correct pin functions on both ends.
