I am installing Symtec heaters under my grips and wiring them to a rocker switch I(hi-off-low) and then to my fuse block (switched). I'm curious is anyone has a wiring diagram they can post showing how to wire the grips to the switch, and where the + and - from the fuse block would tie into the switch? I have the diagram that came with the heaters, but it shows tapping into various leads for power. I'm electrically challenged at times.
