I just installed a Sirius receiver and I hooked it up to the thick Yellow wire behind the base stereo. Unfortunately after hooking it all up I realized that the stupid yellow wire is not switched. How can I hook up my receiver to a switched supply from behind the stereo? I do not want to leave the receiver on and drain the battery.

 

The light green stripe is the accessory line to the stock radio.

 

Thanks man! Worked like a charm.
