Deluxe brown wire option....
on some LT's cutting the brown wire has the bike running on a different spark map that is more suited for hot weather. Some of us live in a place where we have 90 degrees one day and 30 degrees the next, so leaving the wire cut is not the best option...
Radio shack sells a nice Single pole Single throw switch (SPST) that you can easily add to the wire and mount so you can cut or uncut the wire at you whim..
You can pull some slack out of the wire to get more room, I also added some heat shrink with glue to add some more weather protection to the switches connections. Soldering in this small space can be hard, I decided to use a propane soldering iron just to make it more interesting.
Mounting the switch is done in the typical BMW way, a simple tye-wrap will hold it there.
I added a BMW style label so that I remember what direction is normal.
This is not difficult to do, I have 30 years of experience as an electronics and motorcycle electrical expert, so this took me 10 minutes, but if you can run a soldering iron without burning yourself, you can easily do this in a short amount of time. the hard part is the heat shrink tubing, you need a small hot air source to shrink it in that space without damaging other parts, a propane soldering iron typically will have a hot air attachment that is tiny for this exact use, otherwise put 2 layers of tinfoil over everything you don't want damaged and use a larger hot air gun only until the heat shrink insulation shrinks.
