Hi again,
Electrics were never my forte, but have been reading up and think I understand the reason why a Relay is required if I want to use the same/similar switch. So I think I need a 4 pin Relay set up like the diagram below, please someone confirm or set me straight.

I would take the live feed from the Fuse box and the "Light" would be my Fan.
Also...
Does anyone know if the existing switch can be made into a 4 position, there seams to be lots of unused connectors on the back, or do I need a replacement?
