if you remove the shroud around your steering column (3-4 philips head screws) then you will see the actual ignition switch on the left side of the steering wheel. if you look closely at the switch where the soldered ends are... you will see each wire labled (bat, ign 1, acc, starter etc.)
or just get a dmm (digital multimeter) or test light and probe each of the bigger gauged wires to see which wire is hot (has voltage) only when the key is turned to run.
i know this isn't telling you the exact wire but it is showing you how to find it. btw don't use a test light to probe wires on newer vehicles FYI.
