What others have said about the gear indicator, yes. There's an Allen key right on the inside of the right side plastic fairing right by the seat. Snap it off and you'll find an Allen key held in place by a small screw. Use it to take off the seat, and you'll find a number of wrenches and maintenance tools already there.
The gear indicator hooks up to the Datalink connection right above the battery (it's right by the makeshift screwdriver under the seat, and it's got a red clip).
Extra tools needed if not under the seat: a decent set of wrenches of various sizes. Some hex bits of various sizes with a nice low torque wrench that can easily fit in little nooks and crannies. I got these:
I got a set of spool adapters from trex racing and a spool stand from harbor freight. No need to take off my two brothers exhaust. I just put spool adapters where nothing would hit when I used it. (Slightly forward of where they showed to put them in pic they had posted)
