Wiring on a Overhead Flip Down Monitor Help?

[davidc21a]

Hi guys,
Was wondering if I could get some help with wiring an overhead monitor I purchased for my Tahoe. I need help with wiring. I know i should ground the monitor to a bolt under the passenger seat. But......
How does the rear overhead console come off?
Where can I pull the Red ACC power from?
Where do I connect the yellow +12 VDC battery to?
Finally, which wire do I connect to the dome light positive or negative?
Any help would be greatly appreciated.

Personally I'd run the red and yellow front the stereo deck up to it and the other one I'd just use the dome light to the dome light in the front
