I'm assuming the metal bar that goes across the dash behind ac/controls/deck is a simple 12v ground? Ther 're a few braces connecting it to the cab floor so that would lead me to belive it's grounded?

I havn't had a chance to test it yet because my lazy butt is on the computer! Wasn't sure if anyone uses it.


I just need a simple ground for a switch, close to the ac controls
