Shortly after I bought a Burgman 650, I added a Powerlet socket through some of its tupperware, below my left thigh. I used this for five years, and found it ideal for plugging in my heated liner (and Battery Tender, too, as I replaced its SAE connector with a Powerlet plug). It doesn't have the cord get in the way, either while riding or getting on or off; the power connection for most heated gear comes out on your left side; if you choose, you can very easily connect or disconnect your cord from the socket while sitting down, e.g., just about to get going; and you can have a very short cord.
The first pic shows me on the Big Burger, with my TourMaster heated liner plugged in to the socket I added. BTW, shortly after that pic was taken, I gave that cord to a friend, and replaced it with a coiled cord from Gerbing's (the "Extension Cord Coil 90 Deg 4'" found halfway down the page at http://gerbing.com/Products/accessories.php
). If you're really old like me, you might remember those types of cords often found on telephones. This particular cord extends from about a foot to about four feet. I cut off the male coax plug and installed a Powerlet plug.
But I digress. On my XCT, I have the dash cigarette-lighter-style outlet, and I've used that a few times to power my liner (using my existing cord, and Powerlet's "Cigarette Plug To Powerlet Socket Cable," http://www.powerlet.com/product/ciga...socket-cable/3
). I also had the dealer install a Powerlet socket when the bike was new; they put that on the left front, waaay up front (about even with halfway down the front cylinder's finning), and I even used that once.
What I've wanted was a socket in the same place that I had it on the Burger, and I got around to that today. I drilled through the left side cover at what I believe is the only reasonable point to do so. I think it looks fine, with all the other black parts in the neighborhood. Incidentally, putting a socket sort of underneath the tank, in back, essentially eliminates most or all of the advantages of having it below your left thigh -- I want the cord on the outside of my leg, and your leg may block the whole thing, and I have BBob's heat shield in the area, etc.; that is, I'm aware of that spot, and vetoed it. And I don't mind drilling through tupperware.
...If, that is, I could determine the right spot, without screwing up. How I did that -- if anyone's interested in doing the same -- is described in agonizing detail on a page of my web site I just put up: http://www.billanddot.com/victory-xc...in-side-cover/
