My question is where is it and what connector would i need to graft onto the heated grips power supply to plug it in
It's behind the radiator and usually taped to the wiring harness so it may be hard to find or reach. It's the only free connector with black/white and orange/green wires. A Suzuki horn lead will plug into the heated grips connector. Part number 36852-06G00
Also An Eastern Beaver VStrom heated grip adapter from http://www.easternbeaver.com/Main/Bi...om/vstrom.html will plug right in to the OEM connector.
