7 Pin Plastic Trailer Plug - LG1353

7 Pin Plastic Trailer Plug – LG1353

The 7 pin plastic trailer plug LG1353 is a simple, proven connector for trailer road lighting on 12 V towing setups. It’s the standard plug for most older and mid-generation trailers and caravans, giving you reliable connections for tail, brake, and indicator lights. Ideal for garages, fleet workshops and mobile electricians who need a robust, easy-to-wire towing plug that just works.

This 7 pin plug is designed for road lighting only on 12 V systems. It covers the essentials: left and right indicators, tail lights, brake lights and fog or auxiliary lighting, depending on wiring standard. That makes it a trusted choice for light trailers, boat trailers, utility trailers and many caravans still running traditional 7 pin electrics across Europe and the UK.

The housing is durable plastic, so it won’t corrode like bare metal in normal use, yet it’s light enough to avoid strain on the socket. The internal terminal block removes easily after you unscrew the body, giving clear access to each pin. Every pin is clearly marked, so you can wire by colour or by function without guesswork. Once assembled, the cable clamp grips the outer sheath, helping protect the conductors from vibration and pull.

This 7 pin trailer plug sits in that important space between legacy and new standards. Many newer caravans and trailers now use the European 13 pin connector, especially where reverse lights are fitted and legally required, but there are still huge numbers of 7 pin-equipped trailers on the road. LG1353 lets you maintain, repair or build to the established 7 pin format, while keeping your options open to use adaptors or upgrade later if you need 13 pin functionality.

Installation is straightforward. Disassemble the plug body, feed the cable through the gland, strip and terminate each wire into the marked terminal screws, then refit the core into the housing. It only assembles one way, which removes the usual “have I rotated this wrong?” doubt. A competent auto electrician or workshop technician can wire one in minutes, and most fleet workshops will keep a few on the shelf for fast turnaround repairs.
