The TAG Pulse 12 Pin Flat Trailer Plug sits on the trailer side and locks into a standard 12 pin flat socket on the tow vehicle. The 12 pin layout lets you run stop, tail, indicator and auxiliary feeds through one compact connector about the size of a small palm. You can tow box trailers, small campers or work gear where a 12 pin setup is already fitted and just want solid contact at the plug. The body runs a flat 12 pin face with screw terminals tucked under a cover so each circuit stays clamped even after plenty of corrugated roads. The hard plastic housing shrugs off chips from loose gravel and typical road spray around Aussie highways. The tapered tail grips standard trailer cable firmly so the weight of the loom is not hanging straight off the pins. If you already run 12 pin flat wiring this plug is a smart buy to keep the connection tidy.

Q: Is this plug for the trailer or the tow vehicle?

This plug is for the trailer side only. It mates into a 12 pin flat socket that is mounted on the tow vehicle. If your vehicle already has a 12 pin flat socket, this is the style of plug you fit to the trailer wiring. Vehicle-side sockets are a separate piece of gear.

Q: Can this plug be used on boat trailers near saltwater?

Yes, the hard plastic body suits use on boat trailers. You should still keep the pins clean and use dielectric grease to help reduce corrosion. Rinsing the plug with fresh water after saltwater trips will help it last longer. Regular checks of screw terminals will keep connections tight.

Q: Do I need special tools to wire this 12 pin plug?

No, wiring uses standard screw terminals accessed under the cover. A small flat or Phillips screwdriver is usually enough to clamp each wire. Make sure you strip only a short section of insulation so bare copper is fully inside the terminal. Double-check each circuit against your trailer wiring diagram before towing.

Q: Will this 12 pin flat plug fit older 7 pin sockets?

No, this plug only fits 12 pin flat sockets. A 7 pin flat or 7 pin large round socket has a different shape and pin layout. If your tow vehicle has a 7 pin socket you will need an adapter or a matching 7 pin trailer plug instead. Always match plug and socket types so you keep full lighting functions.
