Ring 13 pin to 7 pin socket adaptor – 12V (12N)
This adaptor is a simple, no-nonsense fix when your vehicle’s 13-pin plug needs to mate with an older 7-pin socket. It’s compact, lightweight and built to take a bit of wear and tear, so there’s no faffing about with awkward connectors at the last minute. Ideal for swapping vehicles, borrowing kit or towing a trailer with a different plug standard.
Why this adaptor helps
Got a modern car with a 13-pin towing plug but a trailer that only has a 7-pin socket? This is the bit of kit that sorts that mismatch. It converts the physical plug format so your lights, indicators and other 12N functions line up correctly. Perfect for occasional towing, emergency use or when you’re helping someone out.
- Quick connection: plug the 13-pin into the adaptor, then the adaptor into the 7-pin socket — straightforward and fuss-free.
- Compact and durable: ring-style design keeps the adaptor neat and resistant to knocks and the weather.
- Lightweight: at around 70 g it won’t drag the plug down but feels reassuringly solid.
- Trusted brand: made by Ring Automotive to match typical UK towing electrics.
Technical details
Model: Adaptor (MPN A0036). Dimensions: 15.01 x 5 x 15.01 cm. Item weight: 70 g. Designed for 12V systems and compatible with 12N electrics. Note: this only adapts the socket/plug format — it doesn’t alter wiring logic or add extra circuits.
Installation and compatibility notes
Installation is usually plug-and-play — no tools required. Do a quick pre-tow check to make sure the trailer’s 7-pin wiring follows standard 12N functions (lights, indicators, fog, etc.). This adaptor is intended for 12N wiring on 12V systems; if you’re unsure about 12S or any specialised electrics, have a peek at the vehicle and trailer paperwork first. Also worth making sure the adaptor sits securely in the socket before you set off.
All told, it’s a bit of roadside insurance — handy, practical and made to sort the problem without any drama.
