If the OP meant heated grips. That's what the connector by the radiator is for, it is switched off by the ignition, so if you are old and forgetful like me, you will not run the battery down. I know my Oxfords are supposed to turn off by themselves anyway, but I trust the switched connector more.
The one under the R/H fairing is also switched off, but is meant for lower draw accessories like GPS, as greywolf and others have said.
Yes wire your heated gear, gloves, jacket, etc.., directly to the battery.
