I used the one on my old 1100 to run my Escort radar defector. There are a couple of "open" connectors in the fairing that are 12v, right close to where the wiring connectors(for the lights. etc) pass thru the fairing body. That's where the ciggy lighter socket on mine was wired. Mine was "hot" all the time, but I believe there is one or two that are hot key ON only. Not sure if the wires were for the stereo system head or not, but they were there.
