We do have a BRP 12 volt outlet in the trunk, dealer installed. My Powerlet outlets (BMW-type) are in the dash, just like Deb's.
PowerletProducts Brian used the right angle outlets (I think) but I used the straight ones. Either will work in this location. I wired one to my auxiliary fusebox output, which is switched, and triggered from the BRP outlet wiring. The other is hot all the time, for battery charging. I just tapped into the feed side of my auxiliary fusebox, but added an additional inline fuse for the Powerlet. Too buried for good pictures, sorry. Hope this helps.
