    I need to manually turn on my a/c from the wires behind therm stat

    I have a trane and don't have access to the thermastat my roommate accidentilly locked his door and shut the ac before leaving.

    So I went up into the attic and found the wires from the therstat that go into the ac unit.




    Which wires do I connect together to manually turn on the ac? Do I also have to turn on the fan or does the ac do that automatically? I know its real simple but on this model if you just start connecting random wires you will blow a fuse. Its getting real hot 100'F so any help is much appreciated.

    Service manual and pics attached.
