Overhead panel wiring question

Hey guys,

I'm looking to install a switchpro panel in the overhead liner just behind the existing switch panel. You've probably seen the one in the switchpro thread. Curious if anyone knows of any good docs about how the wiring runs in the headliner down to the main driver side fuse panel - without me having to take everything apart and figure it out in advance.

Also if anyone just knows of a good install writeup on something like this I'd love to see it.

Thanks

 

BUMP! I’m searching for headliner write up too


EDIT: after a morning or searching this is the best i could find, linking to ease the search later

Prettt sure it Runs across to left A pillar

The wiring harness is partially glued down to the headliner moulding. Pulling the headliner out might be the easiest way to get a precise finish of what you are trying to do. Take out both A pillar trims (one bolt on driver, two bolts on passenger behind the handle trim covers). Then I take out the overhead console, sun visors, and rear dome light. I have an AC , and I have to pop the trim covers off of the upper door jams and unscrew two torx heads from each side. Then an additional last panel with one bolt on each side behind a trim cover by the rear seat belts. Pull it out through the passengers side after reclining the seats! I did it when I pulled off my old fabric and replaced it with sound deadening black fabric and it wasn't bad!
