Trailer Wiring Harness,7 Pin Plug,7 Way Wire,6-Feet,Designed for RV Trailers, caravans, Food Vans and Other Towed Vehicles (6 FT) - 6 FT (No Box)

Trailer lighting is not an accessory. It is the only thing telling the driver behind you that you are braking, turning or reversing, and a harness that has gone brittle at the plug is a genuine hazard. This is a moulded 6-foot replacement lead with a 7-way blade plug on the end.

Read the connector type before you order — this matters in Australia

The supplier describes this as a 7-way RV blade plug, and says it is interchangeable with almost any 7-way RV connector. That is a North American pattern. Australian trailers and tow vehicles commonly use different 7-pin arrangements — the flat 7-pin and the large round 7-pin are both widespread here — and those are not interchangeable with a blade plug. Nothing in this listing establishes that it matches whatever is fitted to your vehicle or your trailer. Compare the plug in the photographs against your own socket, pin by pin, before ordering. If they are not the same pattern, this lead will not connect.

The functions it carries, and what is not published

Six functions are named: left turn, right turn, tail lights, reverse, electric brakes and auxiliary. Those account for six conductors with an earth making up the seventh. What the supplier does not publish is which function sits on which pin, and it does not publish the wire gauge for any conductor either. Both of those are the things you would normally check first on a lighting harness. The wires are described as colour-coded and as copper, and the supplier's own advice is to confirm each line with a multimeter rather than assume — advice that is exactly right and that should be followed.

Moulded, hooked and weather-resistant

Construction is a fully moulded PVC shell over the plug body, with metal contacts inside a plastic housing and a hook on either side of the plug to give a grip when pulling it out of a socket. Moulding is the useful detail: it is the joint between cable and plug that fails first on a trailer lead, from vibration and from water getting into a screwed gland, and a moulded body removes that failure point entirely.

Key features

• 6 feet of lead: the stated length, moulded to the plug.
• 7-way blade plug: the connector pattern the supplier names.
• Six named functions: both indicators, tail, reverse, electric brakes and auxiliary.
• Colour-coded copper conductors: as described by the supplier.
• Moulded PVC body: no gland to let water into the plug.
• Grip hooks: one each side, for pulling the plug without hauling on the cable.

Before you fit this

• Australian trailer connectors vary, and the flat 7-pin and large round 7-pin patterns in common use here are not the same as the 7-way blade connector described in this listing. Confirming that the plug matches both your vehicle socket and your trailer is entirely the buyer's responsibility, and it is the single check to make before ordering.
• No wire gauge is published for any conductor. Gauge determines what a circuit can carry, and electric trailer brakes in particular draw real current. Verify the conductor size is adequate for your installation before relying on it.
• No pin assignment is published. Follow the supplier's own advice and identify every conductor with a multimeter before connecting anything.
• No compliance standard, approval or rating of any kind is named, and nothing here states or implies that this harness is road legal or meets any Australian requirement. Trailer lighting is a legal requirement — have the installation checked and tested by a qualified person, and confirm the requirements that apply to your vehicle, your trailer and your state.
• Test every function with the trailer connected, from indicators through to brakes, before towing on a road.

A moulded 6-foot lead with a 7-way blade plug. Check the pattern against your own socket first — that is the question this listing cannot answer for you.
