Car Stereos: Power connection in 2008 Taurus, cigarette lighters, 12v power supply

Question
I'm installing a new Sony satellite-ready stereo in my 2008 Taurus. I purchased a SiriusConnect adapter that requires another 12V power supply (in addition to the one for the head unit). Is there another 12V power supply available without tapping into the power supply for one of cigarette lighters?  The SiriusConnect adapter has just two wires coming out of it (the 12V power and the ground wires).

Answer
Hi Eric,

Whenever I'm installing one of these adapters, I just share the power and ground connections in the radio harness.  The Sirius tuner doesn't require much current to operate, and the power supply in the radio harness usually has enough capacity for both devices.

Hope this helps!
