Are you still using stock amp/speakers? If yes you're already powering the oem antenna module. If no, connect HU blue/white wire to wire at B3 of oem plug.
If oem module is powered and still bad reception you can try an "FM Signal Amplifier" on ebay for under $10. In my '07 it worked pretty good, but in my '12 it didn't help much.
If that still isn't enough, many have had good results with a Metra 44-UA200 for about $20.

If you're using oem amp/speakers, it's powered. If aftermarket amp, you need to connect HU amp trigger wire to wire at pin B3 of the main plug.

I am pulling out an older Kenwood head unit with poor reception and installing a new Kenwood which also has poor FM reception. I assume the antenna amplifier is not powered up. I don't have a wiring diagram for my C6Z. Before I go on a fishing expedition in my dash, how do I identify the amp trigger wire at B3 or main plug?
