No brake lights question

[montypsx]

Hi my mate just told me I have no brake lights, I've checked the other lights all ok, so I've cleaned all contacts which made no joy any way to cut a long storey short I've no power to the brake switchs I've checked in the Haynes Manuel and no wiring drigram for my camper, it's a 1971 right hand drive with 12 fuses. Has anyone got a wiring diagram or can point me in the right direction as were the wire runs and to what fuse etc cheers Phil
