Hello,
I am looking for a source of switched +12V behind the dash on a 04 GMC Envoy. I am adding a integrated Bluetooth Handsfree carkit. From what I can tell, it does not come to the factory radio, which I assume uses the data bus to control on/off via the ignition. Any ideas?
Thanks in advance,

run a wire down to the ignition harness and grab the pink for ignition or the orange for accessory

If you say "I already know how", don't ask me a single question.

Bmnicolosi,
Thanks for the rely! I'll try that; I saw the wire marked 'ignition' in the harness (in a related post) and thought about giving it a try, but was not sure if that was +12 only when cranking, or if it was energized anytime the key was 'on'. From your comments, I'll take it is the latter and will proceed as such. Thanks again!

One other question:
According to the ingition harness diagram, the 'accessory' wire is orange. In all other places in the harness, orange is constant +12V from the battery. Is this true here as well?
