Thanks for the info...but unfortunately no expensive service manual.  

I should have mentioned I have the full sized four door cab...that would have helped.  

Specifically, I was wondering how they fed the electricity to the overhead light console so I'd know what side to run on with disassembling too much as well as any helpful hints to move, adjust, remove, whatever the headliner without damaging it for access to drill.

Thanks for guidance,
Ken

I'm about to drill a hole in the top of the cab of my F250 (2006).  If anyone out there has and information as to where the wire bundles run along the cab and especially to the top of the roof I would appreciate a heads up.

I'd rather use an established channel than mess up and find it too late.

Thanks,
Ken
