Wiring on Mule 2510

I've aquired a Mule 2510 which works fine but someone has disconnected wires behind the steering column, so the cigarette lighter and horn won't work. In particular I could do with the cigarette lighter to work (for tyre inflation and solar trickle-charge equipment etc), but if I could get the horn to work as well that woul be a bonus. Does anyone know what connections I need to make/what colour the wires are to these things?

Thanks
