Wiring route for roof mounted Hellas?
 

Can anyone shed some light (ouch!) on the how to run the wires for a series of roof mounted drving lights on a Disco II? I have four Hella 4000's and a rear mounted work light ready to go on my Safety Devices rack but need to know how the wires enter the vehicle and what general path they take towards the engine bay. Any pictures people may have of their own setup would be huge.

Thanks in advance,

Steve
