You don't want to use the tail light tap on the GT. The CanBus system makes it different than other bikes.
You have three basic options, depending on when you want the fuse block to turn on and off.
1) Tie into the factory GPS lead which is located in front of the battery. This will turn the fuse block on with the key, and keep it on a minute or two after you turn off the key. There is a BMW wiring harness available which means you wouldn't have to cut any wires.
2) Tie into the parking light lead at the top of the headlight. This will turn the fuse block on with the key, and off with the key. There is an aftermarket wiring harness available which means you wouldn't have to cut any wires.
3) Tie into the main low beam headlight feed. This won't turn the fuse block on until the engine is running, and will turn it off with the key. There is no wiring harness available so you would have to cut into the low beam wire.
The details of the installation depend obviously on which way you go. It isn't terribly difficult either way, but if you're not absolutely sure of what you're doing, then get someone who is. Even if you have to pay them, as it's much cheaper than messing up the bike's wiring.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...
