As per title.
Car has 12s/12n sockets, new caravan has 13 pin (yes I already have an adapter!) was just wondering if it is an easy swop of wiring loom, or whether the ECU needs telling at the stealers.

If it is just a loom unplug-swop-replug in, anbody know how much the loom is??

TIA

P.S. looking to use LR parts as have LR fixed bar.

Cue abuse from CG

when i got my new car, and was in the process of arrange the towbar swap, i asked the large one the cost of the 13pin wiring loom and decided to stick with the 12 & 12

IIRC it is a straight swap, but at £120 for the loom i decided the £25 adapter is the way forward if/when the new caravan comes Former Mod/Member, with the most post & Chicken George Arch nemesis

Ta for that.

Have you any idea where the multi-plug is situated (presumebly in the spare wheel well or under the car). I'm wondering if the loom has a 'common half' to connector which either then splits for the 2x7pin sockets o has the one 13pin??

Or am I hoping for too much from LR design

I've looked at this myself - yes it's about £120 for the wiring loom OR... you just wire in a new 13 pin socket on the car for about £10.

Practical Caravan (published by Haymarket George - PObox 666 ''The chicken farm'' N Yorkshire) has just done an awards special magazine, they did a two page article including wiring diagram on changing from twin to single 13 pin. Step by step photo's clearly taken in a barn with chicken p p all over the floor.

sorry i don't know were wiring things are, as my dealer installed mine  Former Mod/Member, with the most post & Chicken George Arch nemesis

The connector block is in the boot on the left hand side (see my gallery picture 11) - If your fitting a LR new 13 pin I would guess it's a straight unplug of the old and replug of the new - If you get it from a dealer ask to speak to the service manager for fitting guidence, if he see's that you've just purchased the kit I'm sure they will be helpfull.

Before I had the FL2 I converted the Merc to 13 pin from 12N/12S by simply taking the two sets of wires off the 12N/12S and conecting them up to the 13pin. As long as you make sure that you waterproof where the two thick 7 core cables enter the back of the socket it should all work fine. Dont forget though that you have to have a seperate earth in the 13 pin for the fridge etc. to work properly! Ralph

Going to do that myself when I get the issue of faulty parking sensors out of the way (Don't want the dealer finding an excuse i.e. suggesting me tampering with the electrics made the sensors faulty).
So I'll be changing the elcetrics over around 2014

I may have overlooked the obvious here, but I was told that when the dealer activates the towbar electrics, they need to distinguish between 7 pin sockets and 13 pin sockets on the diagnostic kit (Land Rover Owner article a few years ago) . Ive no idea why they would do this as the wiring is electrically the same. Anyone had any problems when converting from 7 pin (x 2) to a 13 pin socket?

As RalphK has suggested, if you swap the 2x 7pin sockets to 13 pin yourself, make sure to water proof the back of the socket where the cables enter, preferably with a potting compound. I have heard reports of problems with water ingress where sockets have been changed.

See also http://www.rightconnections.co.uk/13-pin-uk for more info on connection pins and wire sizes (and a wee warning on self-converting).

When I had mine done as per the Auto Electrician I used, he always connected the wires on the back of the socket, before injecting it full of silicon sealant, in twenty years of using this particular Sparky, never once had a problem. p****d off with a Digital Keyboard Warrior

Regarding use of the later single 13pin connector system can anybody comment on whether there is any benefit in updating from the Grey and Black plugs ?
I always think the 7 pins are cheap and cheerful. The back cable grip nuts on mine have both bust.
Also can anybody add further comment on what to pot the car sockets with? Mine is genuine LR unit bought new in January 2013 and its definitely not potted or sealed in either socket; maybe they've stopped doing it.
