I just checked the official Scion 2010 electrical wiring diagram manual and it DOES NOT show any amp/antennae remote output wire. I know that the stock HU has RCA sub outputs and a sub enable/disable option in the settings, but I don't know how they intend to power on/off the amp.

I guess you can just hook up the blue amp remote wire to an accessory power wire (the gray wire on terminal 3 of the middle connector on the head unit itself maybe) and have the amp come on every time the key is on.
