I realize i'm rezzing an old topic but why do you have the PAC wired to the constant 12v and draining the battery 24/7? It should be wired to the red ignition wire not the constant. If it's wired to constant then how will it know when to turn on and initiate the countdown?
EDIT:
You know what nevermind. I started thinking about it. You should be using the blue power antenna wire which starts the timer AFTER the headunit starts up.
Red = Ignition
Blue = Power Antenna
Yellow = Constant
I think the color of your lines confused me
EDIT 2:
No...Checked the diagram aga
