Towbar electric socket question

[steptoe]

All the other cars i've owned have had a standard towing electric socket, my mercedes ( 1989 W124 estate ) has a 13 pin socket, so my trailer light board doesn't fit .

I don't want to change the plug as my other car has a the standard socket -

is my socket the usual mercedes type ?

Hi Steptoe

Mine's the same, and you'll need a 'Y' connector cable to link up to the 12N (and 12S if you have one) sockets on your trailer. All road lights should work fine through the 12N, although in my case I had to insert a fuse to create a permanent live feed through the 12S to my caravan, and have no power to run the 'fridge on 12v when towing. Apparently that will need extra wiring and a split-charge relay, neither of which I can be bothered with.

Y connectors are a bit expensive, if you are just planning to pull a trailer then a plug in adaptor is cheaper, dealer should have one.

I got an adaptor from MB dealer, cost me ?30, about £20. Works a treat. Just keep it in the car all of the time. No need to alter the trailer wiring, the 7 pin plugs just plugs straight in.
