Single Electric – 7 pin

Single Electric – 7 pin sockets are a common wiring configuration used for towing trailers or caravans.

There are 3 types of towing electric sockets to choose from depending on your personal preference and towing needs. They are single 7 pin electrics (12N towing electrics). Twin 7 pin electrics (a combination of 12N and 12S towing electrics). Single 13 pin electrics.

Single electrics with a 7-pin connector provide the necessary electrical connections between the vehicle and the trailer. They allow for the transmission of essential signals, such as lighting, brake, and indicator functions, from the vehicle to the trailer, ensuring proper and safe operation while towing.

They typically consist of seven wires within the towbar wiring loom, each serving a specific function. The most common wiring configuration for a 7-pin connector is as follows:


    • Pin 1: Left-hand indicator
    • Pin 2: Fog lamp
    • Pin 3: Ground (earth)
    • Pin 4: Right-hand indicator
    • Pin 5: Right-hand tail, side, and number plate lights
    • Pin 6: Brake lights
    • Pin 7: Left-hand tail, side, and number plate lights

Single electrics with a 7-pin connectors are compatible with trailers or caravans that have a corresponding 7-pin socket. It’s important to ensure that the electrical system of the trailer or caravan is designed to work with a 7-pin configuration.

In some cases, additional wiring may be required depending on the specific requirements of the trailer or caravan being towed. This could include extra wiring for features such as electric trailer brakes or additional power supply for charging leisure batteries.

If you encounter a situation where your vehicle has a different wiring configuration or if you need to tow a trailer with a different connector type, adapters are available to convert the electrical connection from on type to another.

First Class! Dave and the team are fantastic. The fit on our first Mobile Bike Service and Repair Van could not be any better. From the very beginning, through the design process, all the way to completion I cannot fault a single thing. As I write this, our second van is being fitted to exactly the same specification and the third van is on the way. Long may this partnership continue!

Very helpful and patient with an older guy who was a bit nervous ordering from a company I didn't know. The product I wanted wasn't on their website but I thought it worth asking and they had it at a good price. It came the next day and worked perfectly.

I highly recommend Lee, Dave and the Team at Vehicle Accessories after they did a fantastic job for a one off bespoke van fit for my business. I approached them with a rather radical high concept idea, Dave did a great job taking notes from my extensive brief. He made a great effort to listen and take notes along the way making sure he understood and made suggestions for materials which really led to a much better end product. A particular highlight was a suggestion for them to fabricate a wall mounted Steal Mesh cage system for my equipment which far exceeded my expectations of quality and engineering. During the planning stage and construction suggestions were made to change materials and systems for what they thought would work better for the project as it developed. The end product was perfect and done to a very high standard, it really turned out better than I ever hoped for. Communication throughout was excellent with regular updates, fast responses and easy dialogue when confirming details or discussing changes. Changes were managed quickly and efficiently throughout the build with a great deal of flexibility and professionalism. Even though I was just having just one bespoke build being done for myself I felt highly valued as a customer and treated with the same level of respect and attentiveness as someone ordering a fleet. The quality of work and customer service will certainly mean I’ll be coming back for my next van project.

I can’t recommend Lee and his team of wizards enough. They fitted the gas with all the safety requirements and modified / adapted several parts of the electrics. They went above and beyond my expectations - I won’t hesitate to use them again.

What can say.... the order process was simple, prices competitive and when it was realised that I had ordered 2 incompatible parts I got a call to check and recify the order. Collection was easy and the install team did a quick, neat job. Job done....until next time thank you

Dave, Lee and the team at VA moved crates from my old van to a new one. Easy to communicate with, quick turn around, met all my requests, made good suggestions (such as putting in a waterproof floor) and did an excellent job. Highly recommend.

Big thanks to Dave and the rest of the Vehicle Accessories team. They've done a great job fitting security locks and a floor in my new van. They also moved over my racking and interior lights from my previous van while going out of there way to make it all fit. Excellent service, very efficient and professional. Highly recommended and nice people to deal with. Thanks Miles Ashton Gas
