Towing connectors explained

Three plug types cover most Australian rigs: the 7-pin flat, common on boat and box trailers; the 7-pin round; and the 12-pin, often found on caravans that need extra circuits. When the vehicle and trailer use different plugs, an auto electrician can change the socket or make up a correctly wired adaptor, then test lights, indicators, brake lights and auxiliary functions.

Brakes and the law

Brakes are required once a trailer’s ATM is above 750 kg, and above 2,000 kg breakaway brakes are needed as well. Detail varies by jurisdiction, so check the current Northern Territory requirements with the transport authority, and those of any state you plan to tow through. Electric brakes need a controller in the tow vehicle, properly connected to the battery and adjusted for the loaded van.

Boat trailers and the wet

Boat trailers used at the harbour and coastal ramps are exposed to salt water every launch, and Darwin’s humidity keeps corrosion going between trips. Sealed LED lights, marine-grade connectors and a regular rinse help a great deal. In the wet season, trailers and vans left outside around Humpty Doo or Howard Springs can collect water in plugs and junction boxes, so check them before towing.

Touring setups for the Top End

• Charge lines and DC-DC chargers to keep the van battery up
• Auxiliary batteries for fridges in hot weather
• Dust-sealed connections for unsealed roads to remote areas
• Full pre-trip lights, brakes and breakaway check

Fridges work hard in the heat, so a charging setup that copes elsewhere may struggle here. Getting it assessed before a long trip south or into the parks is good insurance.

Before you call

Have the tow vehicle and van or trailer details ready, along with the ATM, plug types and any battery, solar or fridge equipment fitted. Ask whether the job can be done where the van is stored or needs a workshop visit.
