What else is hot...?

[Evan.]

I need to tap into a wire that's hot when the ignition switch / key is turned one click.

I can't use the audio unit power wire, its already used. I don't want to use the accessory outlet, because I use it already to power something else. So, what other wire can I tap in to? I've tried looking at the diagrams at work and I'd ask a tech, but they've all gone home for the day..

nobody knows?

EDIT:

Use the remote turn on wire from the back of your headunit. Its usually a blue wire.

thanks petey.

Well finally after going through enough diagrams it looks like the option C928 connector (just about the fuses) is open and hot on the ACC switch, which is perfect
