Personally, I ran the wires along the headliner, down the passenger side A-pillar, and to the fuse box, where I tapped into ignition power with an fuse tap (add-a-circuit). Very easy, completely invisible, absolutely no messing with the stock wiring, and can be returned entirely back to stock.
...exactly the same only for a 9500ix with no issues.
