Trailer connectors live in the worst spot on a vehicle — low, behind the wheels, and permanently in the path of road spray and salt. The plastic ones swell, the pins go green, and one day the indicators on the van stop working halfway to the boat ramp. This one is machined from metal instead.
Metal where the plastic ones give up
The housing is aluminium alloy and the pins are brass, cross-slotted so they spread slightly and keep tension against the mating half rather than going loose with use. The supplier describes the assembly as waterproof and says the metal housing resists corrosion and rust. On a towing circuit that is the whole point: a socket with corroded pins does not fail cleanly, it fails intermittently, which is how people end up chasing a trailer light fault for a fortnight. The connection carries lighting and signal power from the tow vehicle across to the trailer.
Which wiring standard you are plugging into
This is a 7-pin round connector wired to the European N-type layout, and the supplier is explicit that it is a 7-pin item, not a 13-pin one. The pin assignment given is: pin 1 yellow, left turn indicator; pin 2 blue, rear fog; pin 3 white, ground return; pin 4 green, right turn indicator; pin 5 brown, right tail and number plate lamp; pin 6 red, brake light; pin 7 black, left tail and number plate lamp. Australian trailers are commonly wired to flat 7-pin or a different round standard, so the layout has to be checked against what is already on the vehicle.
Key features
- Aluminium alloy body: a metal shell in a position where moulded plastic housings crack and fill with water.
- Cross-slotted brass pins: the split lets each pin keep contact pressure instead of loosening after repeated connections.
- Rewireable: the supplier notes it is a standard N-type item and can be wired from a pin diagram, so a damaged socket can be swapped rather than the whole loom replaced.
- Colour-coded pin schedule: all seven functions are published, so the existing wiring can be matched before anything is cut.

What's in the box
- 1 x trailer socket, aluminium alloy
Check your tow vehicle first
- The supplier's copy calls this both a plug and a socket in different places, and the pack list says socket. Compare the photos with the fitting on your tow bar before ordering so you get the right half.
- The pin layout is the European N-type. If your vehicle or trailer uses a flat 7-pin or a different round standard, the two will not correspond and rewiring one end is not always the right answer.
- Trailer lighting is a road-safety circuit. Have the wiring done or checked by a qualified auto electrician, and test every function with the trailer connected before towing.
A sensible replacement if your existing round connector has corroded — provided the pin standard matches what you already run.
