I'm assuming your doing a visor mount scheme. On my '97, I probed around the sunroof switches thinking I could find an ignition hot wire. No luck. Very perplexing. Anyway, plan B. I probed a group of wires coming out the top of the windshield pillar and found what I needed. I tapped into that and tucked the wire in the headliner trim over to about mid visor. I then needed somewhere for a ground and ended up pulling off the pillar trim (the grab handle took an impact driver to loosen the screws). I used a ring tongue connector on a grab handle screw for the ground.
