Heated Grip Wiring?

Just bought a 2010 Tiger with heated grips (factory?). The switch is on the inner-fill side panel, and when I removed it for other purposes the 3 wires came undone. I cannot find any reference as which wire goes to which connector; my service manual mentions 3 wire colors that do not match the wires I'm looking at. Anyone know where I can get that info? Also, is the little heated-grip icon on the switch supposed to light up when the grips are turned on? My user manual doesn't mention heated grips

 

Thanks!
