Power

[Cromeo]

OK Guys, I need to pull 12v power into my cab, but I need it to turn off when I turn the key off... Any Ideas where to hook up at?

The radio is a good spot. Just depends on how much of a load you are trying to pull though your device.

Advanced auto has a 40A relay that I use on my Viair 420C
