My wife and 2 daughters chipped in to get me the OEM heated grips for my birthday this coming weekend, so I did the recommended prep work. It's a bit of a mission, seat, side covers, tank, airbox and headlight all removed, and dug out the electrical supply connector from under the L/H side cover. Had an issue with the airbox, but I'll post that under another topic.
Glad I didn't have to pay a dealer/mechanic to do the job. But maybe they know some shortcuts.
