Your voltage should not fluctuate coming from any good power source on your vehicle as long as your charging system is working. The only variations will be when your engine is running or not. Should be in the neighborhood of 14 v running and 12 v when not running.
If you open the passenger side door and look toward the front inside the door opening near the A pillar, there is a hole about 3/4 inch in diameter filled with foam insulation. You can take a fish wire and run it down thru the A pillar from the top, then poke it through the hole with foam in it. It
will come out right next to your battery. Now you can fish a wire back through and run it right across to where you mirror will be directly from your battery. Put an sPod switch panel in right above your mirror and you can hook additional accessories as wanted or needed.
