I installed my Sirius Satellite radio last night and i needed to find a wire that woudl turn the sirius radio off when the car was off. i searched around on here and i thought i found a post that pointed me to an orange wire going into the radio harness. well when i pulled the radio out there were two orange wires. i choose one and hooked everything up and it wasnt the right one obviously.

is it possible that the other orange wire is the one that will make it turn off when the car is off or is it probably the same thing.

does anyone have the wiring diagram for a 2002 trailblazer or know which wire behind the radio i can use to make the satellite radio come on and off with the car??? thanks for the help.

orange behind the radio is a constant.... go to orange at the ignition switch wiring.....

try using a multimeter probe your other orange wire with the key on you should get a 12v and then turn the key off see if the power goes away.
