Rear cigarette socket install

I'd like to install a couple Of cigarette sockets so my kids can charge their crap while on long trips. I'd like to use the rear of the center console under the cup holders. Can anybody tell me where I can access a wire to tie into. won't be using it for anything other than charging a couple of gameboys or an iPod. Thanks

Run it to the front of the console and tap into the existing power ports.

 

Will there be enough juice in the event that i wanted to use the front and rear in parallel?

 

It's a 15a fuse.
Just don't pull more than a total of 15a and you'll be okay.
If you're concerned that you'll need more, then run one through a relay to the battery and trigger the relay with an ignition-switched source.
