’14 bruin accesory relay

Hi all. I have recently purchased a 2014 bruin 350 for my wife and would like to install a 12v outlet and heated grips.

I am trying to figure out an ignition wire source for my relay so she can’t drain the battery by accident. I installed on mY ’06 kodiak by attaching to the 12v plug and on my ninja 650 by connecting to the license plate light. The bruin in it’s simplicity doesn’t seem to have anything quite so simple.

Any suggestions would be appreciated.
