Plugs, sockets and adaptors
Most Australian trailers use a 7-pin flat plug, older or imported setups may use 7-pin round, and larger caravans often use a 12-pin plug that carries extra circuits for charging and accessories. Mismatches are common when you buy a second-hand van or swap tow vehicles. An adaptor can get you out of trouble, but if you’re towing the same van long term, fitting the correct socket is usually the cleaner fix.
Electric brakes and controllers
Trailers with an aggregate trailer mass (ATM) over 750 kg need brakes, and those over 2,000 kg ATM also need a breakaway system that applies the brakes if the trailer comes off the hitch. Electric brakes only work with a brake controller fitted in the tow vehicle and wired to the brake circuit of the trailer plug. The finer details vary between states, so check current requirements with the WA Department of Transport before you buy or modify anything.
When you book, mention the tow vehicle, the plug on the van and where you’d like the controller mounted. Ask the installer to show you how to set the gain for your loaded van.
Getting ready for a long haul out of Perth
Trips out of Perth tend to be long, whether it’s the Brand and North West Coastal Highways heading north or the Great Eastern Highway towards the Goldfields, and services thin out quickly once you’re past the outer suburbs. A pre-trip check of lights, plug pins, earth connections and brake operation is far easier in the metro area than on the side of the road hours from anywhere.
- Have the charging from the vehicle to the van battery checked, especially if you plan to camp off-grid
- Look at the wiring along the drawbar, where cables flex and collect road grit
- If you launch a boat at coastal ramps, ask about sealed lights and corrosion-resistant connections
Owners who keep a van at home in outer suburbs such as Byford or Ellenbrook may find a mobile auto electrician suits simpler jobs. For a horse float or heavy plant trailer, a truck auto electrician may be the better fit, and if you want a camera on the back of the van, see dash cam installation.
