If by "13 pin connector" you mean the trailer wire plug (we don't have 13-pin connectors in the states, we have 4 or 7 wire connectors) then that cable is no longer available. It has been discontinued for at least five years. There is a reproduction harness on ebay but it may or may not work for you. I do not know if the cable is different for UK models.

Sorry - hadn't noticed two similar questions in one thread from different posters... :rolleyes:

The factory loom is part number 61116906348 - it goes from the 12-pin cnnector in the truck (X393S) to the 13-pin Euro connector.

Yes they are different in Europe

That aftermarket loom (nice find btw) is made by Westfalia which I believe made the original OEM loom.

That’s great report back, just the answer what I were looking for.
Thank you very much for taking the time to put this together top man ��

One other question, would this set up allow you to keep your fridge running whilst pulling caravan as you want to keep your beers cool?
Thanks guys!

There is full-time +12v on the loom, feeding pin 9 on the Euro 13-pin trailer connector (I use this connection to trickle charge my battery) - so you can wire this to the trailer/caravan and then the 'fridge.
