Have plug in towbar electrics for 52plate passet saloon need diagram to wire plug at towball

Hi There.
here are the 7 cable locations and pin numbers.
Pin 1 Yellow L/H Direction Indicator
Pin 2 Blue Rear Fog Lamps
Pin 3 White Earth Return
Pin 4 Green R/H Direction Indicator
Pin 5 Brown R/H Tail & No, Plate Light
Pin 6 Red Stop Lamps
Pin 7 Black L/H Tail & No, Plate Lights

I found the easiest way to locate the correct wires in the loom is to turn on the lights required and use a circuit tester and splice into the main loom where you have enough wire to play with. Try not to cut the loom as it only causes more problems with bad connections and joins.
Good Luck
