12N Electrics OE vs OEM socket
My Electric socket failed during the CVRT (irish MOT) the OE part is €105 and the OEM is €61.

I was wondering if anyone knew if the bolt holes are in the same location on each?

Bolt holes on tow sockets are an industry standard so yes.

Bear in mind with the non-genuine kit you need to fit each wire to the correct pin yourself. The genuine kit is a sealed/potted socket.

Assuming the fault lies with the towing socket (and not the plug/socket in the wheelarch), there is an argument that might as well just buy a replacement 12N socket and replace that alone.  1988 90 Td5 NAS soft top

I had to replace the socket alone as the pins got all rusted up.

Ordered genuine from main dealer and received a Hella branded socket

12N sockets are rubbish, they're always corroding or melting. The 13 pin sockets and plugs are much more reliable.

But yes you can fit either, the actual sockets can be bought for a few pounds. But the kits will come with the back of the socket sealed up with resin. Good quality OEM one will be the same as genuine - less the LR logo on the flap.

Rimmer Bros are expensive. They just charge full retail price on everything. If you get on well with your local dealer you should get it at least 10% cheaper - tell them what Rimmer's are charging and they'll probably beat it for you. Wink

In this case the OEM is not the same as OE - check the photo of the "Britpart OEM" kit. The socket is separate from the loom and not potted/sealed to it.  1988 90 Td5 NAS soft top

That's why I put the caveat in of 'good quality' OEM, Poor quality OEM stuff exists too. Someone can go along to let's say Westfalia, one of Land Rover's suppliers, and say "I want a towing kit for a Defender, what's the cheapest you can produce them for?". It's still made by the OEM but it's not made to the same spec as Land Rover specify.

You can't always rely on Britpart's or even Island 4x4's photos either, what you see in the pic may not be exactly what you receive.

Island 4x4 also being a company that illegally only show's EX-VAT prices when they retail to consumers.... but that's another issue.

I'd just replace the socket, with a decent 12n, Hella branded or similar, no need to go replace the whole wiring loom.

Ideally do the extra wiring and upgrade to the 13 pin as mentioned, it is a vastly better socket design, but also needs more doing to integrate it.

Not necessarily, I don't know what's tested on the Irish MOT. But you can just put the existing wires into the appropriate pins on the 13 pin socket, all you may need to do is connect up the reverse light wire, but this may not be tested on the Irish MOT. You don't have to wire up the permanent live and switched live.

Oh really? I was under the impression on the UK MOT at least, that if a 13pin socket was fitted it had to be fully functional. If that's not the case then my 7 pin will get chopped for a 13 sooner than planned!

If you fit a cover over the socket it won't be removed, they aren't allowed to as far as I'm aware.
When I had issues, I fitted an additional Earth so that's one less issue with a shorther earth path but not something you have to do.
The back of the 12N socket I kept the LR loom but replaced th socket only and filled the back on the socket with a high quality silicone.
Pretty much encasing the conductors in it.

Never had an issue since.

Same things apples with 13pin if required.

For the lights, doesn't matter about the 12v bits. And the only one you wont have a wire for is the reverse light, which isn't tested anyway. It might be different for the Irish MOT though.

From the UK MOT manual;
"On vehicles fitted with a trailer 13 pin Eurosocket, use an approved device to check that the socket is wired to correctly operate the trailer:

• Position lamps
• Stop lamps
• Direction indicators
• Rear fog lamp"


Even 7 pin sockets have the visual inspection, and it's common for them to be corroded, so they can still fail the car on a corroded 7 pin socket.

Not true. From the MOT manual;
"Some tow bar electrical sockets are hidden behind an access panel in the bumper or bodywork. Unless requiring the use of tools or specialist equipment, these panels must be removed to facilitate the inspection of the towbar socket."

Thanks for all the replies, it didn't fail the test on the socket fortunately, It was just mentioned that it should probably be rectified at some stage. The tow bar is only used about once a year to tow a wood chipped about 5k so it's not a big deal.

I think I'll check the wiring first and then see if I need the loom or just a new cap.

Have a look at my post, here -

It shows the differences between Britpart's 'OEM' kit, and a Genuine Land Rover kit.
