Looking for ideas for wire routing to the roof

[DiHrdBowTi]

I'm looking for different ideas on how and where to drill and route wires and such for lights, GPS antenna etc. I have a roof rack that will not be a permanent fixture and will come off at times so anything attached will need to disconnected. Thanks in advance

There is a lot of room in the windshield frame on the passenger side. that's where the washer tube goes up and also the hot wire for the doorpost light. Grommet to the outside with 4 post trailer connector to the rack stuff.

That is also where I've seen people run wiring is inside the windshield frame.
