I added a 12v socket in my right saddle bag using the factory cable/connector.
You can see the details HERE.
It is switched. IOW: only
on when the ignition is
on or in
ACC. And is prewired to the fuse box with a 10amp fuse included from the factory. I intend to use this one for charging devices while riding.
I believe the factory option simply uses this plug/cable to connect to the socket when it is installed. The factory socket option is simply a socket similar to the one I bought at Wal-Mart for my right saddlebag and is mounted in the space behind the right cheek just under the passenger seat, or just behind the right shock. There are mounting holes for the bolts there and an opening for the installed cable to run to get to it. I routed that cable the same for my connection and used the pins I bought for the dummy plug to wire my socket so it can easily disconnect when I need to remove the saddlebag.
I also added another 12v socket under the seat that is direct wired to the battery with an inline 15amp fuse and is always on. My Slime mini air pump needs 15 amps, the factory circuit is not designed to handle that. This one is for emergency use only since I have to remove the seat to use it.
