13 pin to 13 pin extension lead

The only 13 pin socket to 13 pin plug  lead I could find for sale is a metre long on sale at amazon , perhaps a local towbar fitter could knock you something up if you don't want to do it yourself

Not everything comes from Amazon.....

 But at Amazon at its cheaper at £27.99, half the length and is a curly lead but perhaps still a bit long for SPR1968 requirements 

So what's wrong with those on eBay ?

I feel an extension lead and socket will need supporting. Best to speak to a towbar fitter or auto electrician with a view to permanently mounting a second socket or moving the original. 

... the sockets on the cars I've had with detachable bars have swivelled up & down for access and to be hidden. 

Thanks for all the ideas and replies guys they are all very helpful and pointed me in the right direction.

Getting the electrician to modify it was probably the best solution but I needed it quickly 

Ive ordered this one, simply because although its 2m its coiled up which means it’s shouldn’t be to long and I can zip tie any extra length up and out if the way somewhere behind the bumper and then probably zip tie the connector end underneath/at the side if the tow bar so I can easily connect it up  Oh the joy!! Lol   Its amazing what you can do with zip ties!

We are new to modern caravanning and it’s something that never occurred to me, but we’re starting to move site every few days and the thought of scrambling around under the car every time…..

My wife has a range rover evoque and on that the socket drops down as you say.  

Mine is the big range rover vogue, and the electrician said it should drop down the same but it doesn’t its just fixed in place, typically!

I was about to post the same, after a while of non use it does get a bit stuck in the up position, a few sprays loosens it,  I wonder if SPR might have the same problem?

Sorry just seen this, see my reply to ED, over time if not used ours gets very firmly stuck in the up position and appears to be fixed and it takes some WD40 or similar to get it to move again. Have you tried that?
