Lightbulb Auxiliry internal, power, Bluetooth button, cigarette lighters, glove box flashlight

wow lots of word on this title post.

Ok here what i'm trying to do

install 1-2 additianl ciggarete lighter receptipicles(not for lighting cigs)
to power my mobile devices
have a switched power source(using the bluetooth button on the steering wheel)

the locations i am thinking of are: the glove box flashlight receptacle.
and one of the cupholders in the middle console(i'll be using a rubber plug to prevent object or fliud intrusion when not in use)

i am also thinking of having an addininal power tap in the trunk lid area(to power aux light)
possibly controllable with a switch or a fuse)

i have medium electrical knowldege and thats why i am embarking on this project.
any suggestion, links to other posts?

Well, the easiest way is just to 'T' off of the existing cigarette lighter wires (solder, don't wire tap). I believe it's always powered, so you can use a relay to make it switched. There's a low power switched line in the center console, under the cupholders, in the cell phone wiring harness. The wire that is switched is listed in the wiki.

As for the trunk, you could go directly to the battery..
