7 pin to 13 pin conversion
Hi members
I am after some advice please, I have the 7 pin tow electrics already fitted to my 110 but i want to charge my battery through the tow electrics socket and have read that a 13 pin is needed, so if I get one will it be plug and play? If not are there any decent installers who know what they are doing in the west London area...... Thumbs Up

thanks for any assistance. ... Steve

Unless you also have a 12S socket fitted as well as a 12N it is quite an involved job. Yes you can rewire a 12N easily enough into the terminals in a 13 pin socket. However there is no live feed for battery charging from a 12N socket, so you would need to wire one into the 13 pin you will also have to install a relay and have it switched from the live side of the ignition. If you do have a 12S fitted then the wire from terminal 2 is the ignition positive feed for battery charging.
If you do have both sockets fitted then it is just a matter of fitting the wires to the relevant terminals of the 13 pin although they are very close together.

I may have answered my own question , just been underneath the wagon and about 2 foot along the loom from the socket end is a grey plug connection. There seems more wires in the other sides connector than on the tow socket side. So hopefully it is plug and play. Bow down Steve

Usually 12N sockets are wired with cable in a black sheath and 12S are wired with cable in a light grey sheath Thumbs Up

Although new 13 pin multi core cable is also sheathed in black. For those who like Welsh Mountains and narrow boats have a look at my videos and photos at..

Hi gilarion
Thanks for your reply, I've only got the one socket with a black cap if it makes a difference. Steve

If you have a grey socket connection which will be for a 12S socket then it looks like all you will have to do is feed the core cables from that connection block to the new 13 pin socket following the wiring diagrams given. If you have to join the cables with a new length of wire make sure you use good quality connectors and not those awful scotch block things. It may be possible to buy the socket feed with the right connector to connect to the connector you have that would make it so much easier. For those who like Welsh Mountains and narrow boats have a look at my videos and photos at..

What year model is your 110 as there are wiring kits available from Land Rover for wiring a 13 pin and also a 12s but their part numbers differ depending what model and year. For those who like Welsh Mountains and narrow boats have a look at my videos and photos at..

The 12N socket is plug and play and is what you describe.

The 12S wiring is not fitted as standard but is what you need to do what you want. It is reasonably involved to add the 12S wiring and involves wiring back to the battery box and taking an "ignition on" signal from inside the dash.

If you had both 12N and 12S, you could very easily fit a fully-wired 13 pin socket. With just the 12N, you could easily fit a partially wired 13 pin socket which would be fine for towing a trailer, but not for what you want.

thanks me being a clueless git I hope I can plug and play, just need to know the best place to get the kit... obviously OEM would be great but with the LR price tag there must be a good alternative. Steve

I've brought the 13 pin kit now,so my question is is it easy to fit? I already have the 7 pin system fitted on an year 11 plate.

An idiots guide would be very helpful Thumbs Up Thumbs Up Steve
