connecting a blue tooth receiver to clarion (OEM) stereo for 2006 Challenger 180 CS.

I need to connect to a “hot” 12v wire and ground, in addition to the RCA plugs for speakers. My question is which hot wire to use in the glovebox? I want power to the BT only when the stereo power is on. There is a heavier gauge orange wire available going to the stereo, but I think that might be unswitched. Can anyone help?

Sure buy a cheap test light and see which one has switched power
