In the rear of my 2016 F56 I have a spot to put in an aux 12v socket. It is a spot intended for the Storage Package plug, but is just a cover for the cars with out the storage package. I have the socket I need but no directions for wiring. Can anyone tell me if it would be OK to wire the plug to the light, which is right next to that location, in the rear on the right hand passages side of the trunk area??? Or better, what or where I SHOULD tap into. I successfully opened everything up and found NO open / available plug / wires to tap into, just tons of wires tapped together in bundles? I know I need a Hot and a Ground, but which ones?? I do not want to splice into just anything, and make a huge mess. I am sure that SOMEONE else, much smarter than me already has accomplished this??
