Yes, The center pin of the male RCA jack is the hot terminal when conected to the factory socket. I used to use the accessory outlet with the RCA cord adapter for my heated sheild. I thought about reversing the polarity on the accessory socket to make the male RCA pin the ground, but I did not want to have a backwards polarity accessory socket in case I wanted to plug in a GPS or phone charger. Therefore I hard wired a dedicated RCA jack just for the heated sheild and I reversed the polarity making the center pin ground and the outer part of the plug hot. This way if you unplug at the helmet and drop the cord onto your running board it will not short out. My dedicated RCA jack is wired direct to the battery with an inline fuse so I can leave my helmet plugged in when I take it off on trail stops and the sheild will stay warm with the sled turned off.
I also re-wired my accessory socket straight to the battery with an inline fuse so that I can have my GPS on during trail stops or charge a cell phone with the sled turned off.
