A GPS unit is a great CAR accessory, but the power cord hanging across the dashboard is an eyesore. Many vehicles have 12V power at the rear-view mirror, with a 2-wire plug. Tap into it to straighten up your view.

You will need:

  • 12V power receptacle I used the Philmore TC600 cigarette lighter plug socket.
  • Wire, 2-conductor, insulated, 20-gauge solid, 6″ such as bell wire. Or 2 lengths of single-conductor wire.
  • Cable ties (5) aka zip ties
  • Wire cutter/stripper
  • Soldering iron and solder
  • Ohmmeter or multimeter
