I waited to be finished before confirming the info, but I just finalized the install with
the same wires that scparts indicated. I originally tried the black & white for 12V (no multimeter at my house) that Speedy recommended, but I was only getting intermittent power for some reason. Someone has to say it: it was a real mofo to do. One of the pins wouldn't slide in (you have to find the right way to insert it - it's 10 times worse than prom night) and I of course broke it. I cramped up, busted my fingertips, banged my head against the glass - hello, greasy prints - and swore enough to scare my neighbors and scar their kids for life. So I had no choice but to splice, and this without pulling the gray connector (it wouldn't come out and I opted not to rip off all the wires by accident)... which felt like performing field brain surgery on a mouse while upside down on a trapeze with a flashlight in my mouth.
Now that I'm done, and it took me several tries over 2 days, it's an AWESOME setup and you HAVE to do it. The cord running from the bottom outlet gets in the way and draws too much attention. But if you're as clumsy as I am let someone else handle it. I'm just too OCD to let some dude climb all over my brand new interior and I hope that my account at least amused and prepared you guys. It's way worth it.
