This TAG 7 Pin Flat Socket (Vehicle Side) steps in when you want a standard 7 pin flat outlet on the towbar for lights and electric brakes, with each of the 7 pins handling a single trailer circuit. The female housing bolts to the bar and mates with a flat trailer plug like UNT035, giving a known wiring pattern across brake, tail and indicator feeds in a normal 12 V towing setup.

The body uses a solid plastic housing, a metal spring clip and two fixings, with a compact footprint that sits neatly on most towbar mounting plates. Inside you get numbered screw-style terminals, so each of the 7 connections lines up with the matching wire in a typical 7-core trailer cable. The hinged cover shuts over the face to keep dust and spray off the pins when you get out there on wet or dusty roads.

Q: Is this socket the vehicle side or trailer side of the connection?

This socket is for the vehicle side. It mounts on the car or towbar and the trailer carries the matching plug. That means your wiring loom on the vehicle feeds into the numbered terminals on this socket. The mating 7 pin flat plug on the trailer then connects into the face. This keeps the socket fixed and the plug mobile.

Q: What trailer plug part number is this socket intended to match?

This socket is intended to match the TAG 7 pin flat trailer plug part number UNT035. The face layout follows the same 7 pin flat standard so any compatible flat 7 pin trailer plug can connect. Using the matching TAG plug helps keep pin alignment and sealing consistent. It also keeps the full harness kit within the same brand range.

Q: Does this socket include internal numbered terminals for each circuit?

Yes, the socket includes numbered terminals for each of the seven circuits. Each terminal lines up with a standard function such as tail lights, brake lights, indicators or electric brake feed. The numbers are moulded or marked near the screws inside the housing. This layout helps reduce wiring mistakes during installation.

Q: Can this socket be used on different tow vehicles and brackets?

This socket is suitable for use on a wide range of tow vehicles that accept a flat 7 pin trailer connection. The compact housing works with many common towbar mounting plates that allow a flat socket. Installers can position it where the trailer plug can reach without strain. The standard 7 pin flat pattern keeps it cross-compatible with many trailers.

This TAG 7 pin flat socket suits the vehicle side of a standard 7 pin trailer wiring connection. The socket mounts to the rear bar or towbar area where a flat 7 pin trailer plug can be reached. Numbered terminals inside the housing accept individual trailer circuit wires from the vehicle loom. The socket is intended to mate with the TAG 7 pin flat trailer plug part number UNT035 or any compatible flat 7 pin trailer plug using the same standard layout.
