Hopefully this will make sense and help you out!!!
white wires from the dash switch goes to the jamb switches and the switches should be self grounding.These should be the same white wires that run to every interior light.As these act as the ground wire for each light which is triggered by the light switch.
The orange wire should be hot coming from the fuse panel,this goes to every light as well,but not the door jamb switches.
Hope this was helpfull!!!
