On the 2001 & up it would be for a low watt running light required by a couple of markets. Don't know if the earlier ones had that provision or not, but that'd be my guess.
If it's the small gauge like the turnsignals use, I wouldn't use it to power heated grips, but it could be used to control a relay for them.
