    Hi everybody.

    I wish to take off the Pollak 7 Way towing electrics socket from my imported F250 and replace with a standard UK "N" socket. The trouble is that when looking on the US websites, I am getting two versions of the wiring configerations.

    Cable Colour Version 1
    White - Ground
    Green - Right indicator
    Yellow - Left indicator
    Black - + 12v
    Brown - Running lights
    Blue - Electric Brakes
    Red/Orange - Auxillary

    Cable Colour Version 2
    White - Ground
    Green - Running lights
    Yellow - Auxillary
    Black - + 12V
    Brown - Right indicator
    Blue - Electric brakes
    Red/Orange - Left indicator

    The indication on the Pollak plug top is that it is wired as per version 1 above - however which is correct?

    Also beside the Pollak connector there is a 4 way flat moulded connector - what is this for?

    There is no provision for reversing or fog light and i wonder how this is accomodated?

    Does anyone know or can help? Many thanks

    easiest thing to do is invest in a cheap multi tester.

    connect one probe to chassis/known earth point and , in turn, turn on each light and probe the existing socket to see which pin/tube becomes live....note the wire colour then move on to the next function.

    fool proof :thumb:

    I was going to suggest the same.. if you haven't got a multimeter use a 12v lamp with a couple of wires soldered on to it .. easier to see than a multi meter .. and simpler to use..

    Sometimes I prefer using a lamp when fault finding.. unlike a meter it pulls a load and will help identify poor connections which you might miss using a meter.

    Don't quote me I may be wrong but I thought the flat connector was the power for fridge/freezer to supply 12v for when travelling (because of size of American fridge/freezer to much power draw for conventional plug socket).Hopefully someone will come along & put us both right.:thumb:

    Not much help but a caution..

    I've got a 98 ZJ Jeep, UK spec etc came with UK tow bar etc. Plugged in our trailer, known good/correctly wired electrics and, all OK except, indicators on relevant tail light flashed, ie right ind and tail flash yet left tail just on, typical of American vehicles in some States/or maybe just older vehicles don't quote me. 'Fiddled' with wirring and found who ever had wired had used the American trailer block/connector on the chassis which was wired for the flashing ind and tail as above hence wrong for here. Back to basics and popped lights off and picked up feeds direct, one to watch maybe and easier identified by the above mentioned bulb method.

    I take it the truck has been converted to UK wiring specs??

    You should have an after market foglight and the indicators at the back should flash yellow with no effect on the tail/brake lights??

    Hi there here is a good web site for american vehicles plugs,harness adapters and wiring help.

    Home :: Hopkins Towing Solutions

    i used this site when changing my plugs over also used a test lamp:thumb::thumb:
    One thing i did change with not having any fog lamps on my trailer i used that terminal for the electric brakes on the trailer:thumb::thumb:
