Variable Heat Controller - VHC-2 for heated grips Has a click-detent off position, a feature absent from our previous aluminum bodied controller. Panel mount only, just the knob will show above the panel mount location you choose. NOT intended for handlebar mounting, NOT for Yamahas. Easy two wire installation, red wire is for power source, black is output to the grips. Eliminates the toggle switch and resistor for any heated grip installation.
