ETUKER 7-pin pre-wired towbar socket with 1.9m cable (metal) – 7MZ
Product description
What it is and why people buy it
ETUKER’s 7-pin pre-wired towbar socket is a metal 12V trailer connector designed for towing setups where you want a ready-to-fit electrical connection with a decent lead length. In plain terms: it gives you a 7-pole socket for your trailer/attachment so the car can power lights and the usual trailer electrics.
Because it’s described as pre-wired and comes with a 1.9m cable, it’s aimed at reducing the faff compared with sourcing a socket separately and then figuring out wiring. That matters if you’re doing a DIY install (or you’re organising a mechanic) and want a straightforward path from “I’ve got a towbar” to “I can plug the trailer in”.
The essentials (based on the provided details)

This model is listed as a 7-pin towbar socket in metal, with an included 1.9m cable. The base description also calls it 12V, waterproof, and compliant with CE and RoHS.
A key thing to bear in mind: “waterproof” is helpful wording, but trailer connectors still spend their lives in wet mud, spray and road grime. So it’s worth being sensible about how/where the cable and connector sit once fitted, rather than assuming it will shrug off everything in every installation.
Also, the name includes “7MZ”, which likely relates to a specific compatibility variant, but the entry you provided doesn’t spell out exact fitment details (for example, which towbar wiring harness it matches). That means you’ll want to double-check your existing plug/wiring situation before ordering.
What you’ll notice day to day



The practical difference with a pre-wired tow socket is mainly installation speed and layout. With a 1.9m cable, you typically have enough slack to route neatly without everything running under tension.
For example, on a typical setup you’d run the cable along the towbar area and bring the socket into a position where you can reach it comfortably when attaching a caravan or trailer. If the lead is too short, you end up with awkward routing, if it’s too long, you end up with messy slack. Here, the stated 1.9m should feel reasonable for many common installations—though your vehicle and towbar mounting location will decide whether it’s “just right”.
Where it shines
- You’re looking for a 7-pin trailer electrical socket with a cable included, rather than building the kit yourself.
- You want metal construction for a towbar-mounted point where the connector can take knocks during loading/unloading.
- You’re aiming for something that’s positioned as waterproof, with CE and RoHS mentioned in the listing.

Limitations and who should avoid it
It may not be the best move if you need confirmed compatibility with an existing specific harness/connector. The listing name suggests a particular variant (“7MZ”), but there are no explicit compatibility notes in what you shared.
It also might feel like overkill if you only need a basic replacement and already have your wiring sorted, because pre-wired sockets are most compelling when you’re starting from a simpler “missing socket” situation.
If you prioritise the tightest, most seamless professional-level fitment, you may want to check with your installer or compare what your car currently uses—because even with the right number of pins (7), the physical/wiring side can differ depending on the vehicle and towbar setup.

Should you buy it?
Buy it if you need a 7-pin towbar socket for a 12V towing setup and you specifically want a pre-wired metal socket that comes with a 1.9m cable, so you can plan a tidier install without hunting down separate parts.

Don’t buy it if your main concern is confirmed fitment with your exact vehicle tow electrics, because the information provided doesn’t list detailed compatibility requirements. In that case, it’s smarter to verify what plugs/wiring you already have before committing.
This one tends to make sense for DIYers who prefer a packaged solution and for anyone replacing a worn or missing socket where having the cable included is genuinely helpful.
Mini FAQ
How long is the cable?



The listing states a 1.9m cable length.
Is it suitable for wet weather?
The base description says it’s waterproof, which is reassuring for outdoor use around the towbar.
Does “7-pin” mean it will suit any trailer?
Seven pins is the standard for many trailers, but matching still depends on your towing wiring/vehicle setup. With no explicit compatibility details provided here, it’s worth double-checking your existing arrangement.
What is “pre-wired” useful for?
It generally means the socket is supplied with wiring already set up, which can save time versus sourcing a socket and then wiring it yourself.
Final verdict
If you’re trying to get a 7-pin, 12V towbar electrical point sorted with a metal socket and a ready-made 1.9m cable, the ETUKER 7-pin pre-wired socket is a sensible, no-nonsense option on paper. Just don’t assume compatibility from pin count alone—check your tow wiring situation first, and you’ll avoid the classic “it looks right, but it won’t plug/work the way you expected” problem.
