should be a fairly simple of case of changing bulbs to 12V then removing the nato plug and associated cable replacing it with a 7 pin and associated lead into the junction box. within the junction box you'll need to link some of the circuits together that would otherwise be split across 2 or more pins on the nato plug.
a bit messy within the junction box but if methodical about it then its quite straight forward (after all I managed it) if a little time consuming. alot easier done from above once the tub is removed  |

James, pm Wiggs on the D3 site, he will point you in the right direction
Your more than welcome to have a look at mine as well even though it was already done when I bought it. You cannot teach stupid people to do clever things |

Hi,
hope this helps "To convert a Sankey from 24v to 12v all you need to do is swap over the bulbs and change the plug so it fits into a civilian socket. The 24v bulbs are as follows: Indicator/Fog/Running lights: 24v 21w Stop/Tail lights: 24v 21/5w Replace these with the 12v equivalent and job done. Next job is to remove the 12 pin military plug and swap for a 7 pin12N civvy plug which plugs into the ES01 socket. The wires are as follows: Military Spec wiring Wire Letter/No. Function Pins on 12N [Pin A] wire #1 Spare not used on 12N [Pin B] wire #2 Left hand Stop Pin 6 / Red [Pin C] wire #3 Convoy not used on 12N [Pin D] wire #4 Earth Pin 3 / White Pin E] wire #5 tail and number plate light Pin 5 (RH Tail/Brown) & Pin 7 (LH Tail / Black) Pin F] wire #6 Fog lamps Pin 2 / Blue [Pin H] wire #7 Spare Not used on 12N [Pin J] wire #8 Right hand stop Pin 6 / Red [Pin K] wire #9 Aux Not used on 12N [Pin L] wire #10 Earth Pin 3 / White [Pin M] wire #11 Left hand Indicator Pin 1 / Yellow [Pin N] wire #12 Right Hand Indicator Pin 4 / Green" Taken from http://landroveroneten.com/index.php/2009/...n-trailer/ Jack |

Either make up a short adaptor (sankey socket to pin!) or what I did was bought a trailor light board and lead/plug and simply took the light board off and wired up the lights and tied the lead up to the front of the sankey - job done for £20

My advice although it doesn't fit into cheap, is if you haven't done anything yet then consider using the 13pin euro plug and socket for both car and trailer.
you can then have both a battery feed and ignition feed in the trailer to charge the trailer batteries whilst you are driving, Also these connectors are waterproof. i have also run an alarm circuit in there so that the vehicle alarm is triggered if the trailer plug is removed when the alarm is set. You can get 13pin to 7 pin adaptors if you want to use other trailers. |

Thanks for all the advice guys. It doesn't sound like as difficult a job as I had thought. I think I will probably do as Zagato has suggested re a trailer board.
Ken, many thanks indeed for the offer. The only issue is my 90 is not LEZ compliant, therefore I don't think I will be able to get the trailer in to West London. 
Thanks again all, James |

If I recall correctly mine was 24V when I bought it (from the last ever Ruddington auction). I towed it home behind my 80" Series I (my daily driver at the time) with a trailer board, and then fitted a NATO electrical socket to the Land-Rover. The only alteratin to the trailer I made was to swap the 24V bulbs for 12V ones - in the days of the narrow-track trailers (and probably still to this day) this was the only difference.
In the fullness of time, and with the acquisition of other tugs, I decided to convert to a standard 7-pin connector. To do this I mounted a 7-pin trailer socket on the front crossmember of the trailer (between the legs of the A frame) and wired it into the junction box on the back of the crossmember (which, although it used sealed military bullet connectors, also accepts standard civvy bullets). I also removed completely the original NATO plug and lead (which I still have somewhere - they were rare as hen's teeth at one time). Finally I made up a short lead to connect the socket on the tug to the socket on the trailer using a length of 7-core coiled cable which I happened to have (coiled like the air lines on HGV trailers), perfect for the job. This meant that when the trailer was not in use I could remove the jumper cable completely and keep it safe; it was a totally-reversible modification if I wanted in the future to restore the trailer. Ultimately I sold the Sankey, mainly because it was so damn hard loading or unloading it (the early ones didn't have a tailgate, so everything had to go over the side), and replaced it with a more useful ex-BT trench-digger trailer. One unusual feature of my Sankey was that it still had all the wading plugs in the bottom, and I always wanted to see if it was true that they could float with a full payload! Unfortunately I never had the opportunity. It always struck me that this was one of the most pointless Army requirements - the Land-Rover won't float, so why have a floating trailer? Never understood that! |

As above. Just swap the bulbs and the plug.
I did all the wiring in the plug rather than changing back at the junction box because I wanted to keep the insanely long, flexible harness (and the ability to convert back if necessary/convert to 13 pin at a later date). Colour coding for Sankey plug is: [Pin A] Red/Brown = wire #1 = Convoy = not used on 12N [Pin B] Green/Purple = wire #2 = Stop = Pin 6 / Red [Pin C] Red/Brown = wire #3 = Convoy = not used on 12N [Pin D] Black = wire #4 = Earth = Pin 3 / White [Pin E] Red/Orange = wire #5 = Tail = Pin 5 (RH Tail/Brown) & Pin 7 (LH Tail / Black) [Pin F] Red/Yellow = wire #6 = Fog = Pin 2 / Blue [Pin H] Red/Brown = wire #7 = Convoy = Not used on 12N [Pin J] Green/Purple = wire #8 = Stop = Pin 6 / Red [Pin K] Purple = wire #9 = Aux = Not used on 12N [Pin L] Black = wire #10 = Earth = Pin 3 / White [Pin M] Green/Red = wire #11 = LH Indicator = Pin 1 / Yellow [Pin N] Green/White = wire #12 = RH Indicator = Pin 4 / Green Join A,C & H together. Join B & J Join D & L K is the aux permanent 12v feed. You won't need that unless you plan to add some extra gubbins to the trailer. If so, it might be better to swap to 13 pin S-type electrics on the Land Rover. Whole job: 1 hour (+ the inevitable 3 hours of fiddling around as one of the bolt heads shears off and you cut one cable too far down...).

There's a German guy on the Ex Mil Land Rover forum who's selling brand new NATO sockets complete with about 3' of cable. Easy to splice into your existing vehicle wiring.

I would personally strip all the wiring out and rewire it with 7 core, based upon I know how crap the original wiring is after 24yrs as a mechanic in the army.

Is "Wiggs on the D3 site" the guy who is/was converting a Sankey to a camping trailer? Have you a link so we could have a look?
