Towbar electrics wiring

[froggy]

Have decided to refit my tow bar and electrics but when i removed them i just cut off the wires and now cant remember how to connect then back up.
Does anyone have a wiring diagram for a standard 7 pin towbar socket?
Have tried a search on here but nothing came up
