Questions about the stock wiring harness points

Hello. Thank you for all the great ideas I have gotten here so far.

I have just joined this forus after stalking it for some time. The ideas I have come away with have been great. Here is my intro:

In my investigation of factor plug in points, I found this open plug behind the tilt out compartment by your left knee....where the interior fuses are:

Does anyone have any idea what that might tie into?

I also found the power mirror wiring in the dash, just waiting for a swith. As the look in the cab looks like it is all the same, can anyone advise if the same holds true for the door? I hate pulling door panels (really, I really really hate it) so if someone could let me know if the plug for the power mirror is in there, I would owe you a beer....or five.

I look forward to reading more. I am installing a Curt receiver hitch next week and will take photos as I go. I got the Curt wiring harnes so I do not have to cut factory wires (another thing I hate doing) and will let everyone know how it goes.
