Took a moment to figure out the best way to install this, but with a $7 Fuse Tap from O'Reilly Auto parts, I just tapped into the fuse box of my car and then found a screw connected to the body for the ground - I popped off the interior panels and concealed the wires, so you can't even tell it's there practically - Works great and so much better looking and functional than having a cable running from the cigarette lighter

I couldn't find a really clean way to install the box without some of the wire being exposed

No way was I going to waste my time with the cheap 10 dollar kit sold here
