I have the ArcticBomb one with a switch. It took a few tries to get the right one to make it work on mine but it works well now. I have had transmission error pop up a couple times, I believe it is related to the charging system and power usage effecting the signal voltage like Airdam was saying. Not sure that it would matter if you have the Switch or Switchless. Only advantage with the switch is you can turn it off and run "stock" without any errors until your system voltage comes back to normal.
