I just looked closer at my mess of a switch and it looks like there are two rocker switches, The grip heater rocker switch is there and there's terminals from a missing rocker switch right next to the grip heater switch. This rocker has a Black/white wire on one tab and an orange wire to a tab and then there's a grey wire and a green/purple wire just hanging.. The Clymer manual electrical diagram isn't too clear as the multifunction switch is represented as a box with 12 wires going to it and some are grouped and two are connected right next to the switch. I think the Clymer electrical diagram is wrong also because it only shows a green/white going to the grip heaters and a green/purple going to the seat heater.. I know the grips have two heat settings I suspecte two wires for two elements) and under my seat I have a 3 wire connector half with brown (ground?), grey, and black/white. I suspect the orange wire in the right control multifunction switch is the power for seat heater and then it sends it out to the grey and the black/white. I can test this but again, does an LT right control multifunction switch have a seat heater switch? HMMM, I just found the seat heater circuit diagram and it shows the green/purple bringing the switched power to the seat heater switch.. so that orange wire goes to something else.
