It most definitely is. It's not stock. I know because that's exactly the same place and the same way I installed the wiring for my Gerbings heated gloves, with the exception that the connector is pointed up to make plugging it in and out easier while on the bike (and if I get off without disconnecting it,. it will pull out easily). Maybe the dealer did a shakedown ride while wearing heated gear?That looks dealer installed to me.
This is a picture of the Power Let Socket I installed a couple weeks after acquiring the bike. Simple install and now can keep on Optimizer and hook up for heated gear.
