12V 7 Pin Trailer Plug Male

This metal 7-pin trailer plug is a direct replacement for a damaged or worn plug on trailer, caravan or implement wiring, and works equally well for wiring up a brand-new connection from scratch.

Built for 12V systems, the metal housing stands up to daily hitching and unhitching better than a plastic equivalent, and it mates with any standard 7-pin trailer socket.

Dimensions and installation

• Pins: 7
• Voltage: 12V
• Housing: metal

Tip: pair this with the matching ST7PL female socket if you’re wiring up both ends of a new connection rather than replacing just one side.

Compatibility

Fits any trailer, caravan or implement using a standard 12V 7-pin connection.

If you’re unsure whether your setup uses a standard 7-pin plug, contact us before ordering.

Also suitable for other machines?

Yes — the standard 7-pin trailer connector is used across a wide range of trailers, caravans and farm implements, not just tractors. Contact us if you’re not sure your setup matches.

Why a metal housing matters

Durability under daily use:
A plug that gets hitched and unhitched regularly takes a lot of physical wear. A metal housing holds up to knocks and repeated plugging far better than plastic, so pins stay properly aligned over years of use.

Standard pinout:
Using the standard 7-pin layout means this plug works with the tail lights, indicators and brake lights already wired on most trailers and implements, without needing to rewire the circuit.
