Who is using aftermarket grips and grip/bar warmers?What kind of heating element did you use and how did you wire it?Using the stock heater circuit or a toggle switch?
I bought some from a local dealer . I wired the two hi and low into the stock positive circuit. The one that piggyback from the left and right grip. The ground wire has individual wires for both left and right. I soldered the aftermarket grips in to the stock bullet connectors. This was a 98 srx700
With 300 watt mag I suggest running the RSI Hi Power elements with Hi and Low tied together and run them in parallel instead of series. Just connect to the stock rheostat. You should be around 2 - 3 ohms resistance compared to around 3.8 - 4 ohms for the stock elements.
