I was told, when I bought my LT, that the power outlet on the bike would allow me to plug in heated clothing among other things. -- I've got that.
All of the jacket liners I see require a heat controller of some sort. This avoids the "full-on" or "full-off" issue. -- I've got that.
What I'm confused about is the fuse and battery connectors as in this image:
Why would I need to connect to the battery if the powerlet connector is already there?
: what you took a picture of doesn't go in the accessory plugs, it gets wired directly to the battery.
You have two "BMW/European plugs" on the LT for power, one by your left shin as you sit on the bike, the other by the passenger. Both allow you to power up accessories that have "BMW" or "Euro" plug ends (as opposed to conventional 12 volt accessories that are larger in diameter--think "cigarette lighter" accessories like you'd use in your car, like a cell phone charger, radar detector, etc.)
If you want to use a conventional 12-volt-ended accessory in either of those, you need an adapter that essentially reduces the size of the plug so it fits (you can get these at the BMW dealership or online--many of the vendors on this site sell them as well).
What you have in your picture is an option to permanently wire up your vest/heated garment, directly to the battery. The item on the right would wire up to the battery (or better, to a aux fuse box like the blue sea), and you'd have a foot or two of wire that you can keep under the seat. When you want to use your heated garment, you'd then attach the device to the left, plugging that into the device on the right (which is fused) on one end, the other end into your garment.
When you're done riding, disconnect the heat-troller (or whatever the manufacturer calls the device on the right) and stash it in your top box or garage), lift your bike-s seat and tuck away the wire from the part on the right of your picture, and you're good to go again.
Permanently wiring up a set-up like this one has a couple benefits. One, you're fused, so there's an added level of safety (for you and your bike's electrical system). Two, you don't have the wires crossing your legs or your passenger so you won't be as distracted when you ride. And three, it gives a "cleaner" look, as the wires go straight from under the seat to your, uh, "seat" I guess.
