A little additional information since the subject was brought up:
The light blue/black wire is the main power lead for the power windows, moonroof, and rear slider. It is fed by fuse 601 in the central junction box and is fused with a 30 amp fuse.
There are also two pink wires coming off of the central junction box that are both fed by fuse 42, which is rated at 15 amps. One of these wires is the power circuit for the power door lock switch, and the other runs to the radio and serves as the "turn on" signal. The radio uses very little current on this circuit as it is mainly powered by fuse 11. The pink circuit can be used for light-load accessories and as an amp turn-on lead.
FireMe,
My truck doesn't have all that fancy stuff like a moon roof or power sliding rear window. It does however have power windows and locks. is the end of the wire that goes to the fancy stuff taped off somewhere, or does it just end in a harness plug somewhere. Just kinda curious.
Beerstalker,
Are you able to unbolt your fuse panel? I'm not sure about the 07's but If it was like mine all it takes is a 10mm (I think) socket and 4 bolts and you can pull that sucker down and see the back of all the harnesses coming into it. Then use a test light and play around and maybe you can find something. First I'd look for the blue w/ black wire over on the left side of the back of the panel. Its on a 30 amp fuse - surely thats big enough for your monitors?
