    Hey, I'm trying to install my new head unit and can't seem to find a radio wiring diagram anywhere. Can anybody tell me which wire on the 4 plugs are 12v, switched 12v, and ground please. Thanks.

    I just installed a Pioneer AVIC-X930BT using Metra Wiring Harness Part# 70-1761 and the Pioneer supplied aftermarket wiring harness for the unit. The Metra Harness has the color codes on the packaging after soldering, or splicing, all of the connections to the Pioneer supplied harness you just plug the factory harness into one side and the Head Unit side into the new aftermarket head unit. I didn't worry about factory wiring colors.

    ^^^ What he said.

    The TTORA site has some diagrams online that will work. IIRC, the plug with the front speaker wires also has a gray wire (switched), a blue/yellow wire (12V) and a brown wire (ground). With a VOM these should be easy to verify.
