This is the first time for me installing radio in a Honda, I have a sc, I bought the antenna adapter and it has a blue wire for power, also the harness adapter has the blue wire for power antenna that leads to the LX needed green and yellow wire and the pioneer AVH-P4000 does not have a antenna power out, it said to use the system control out which I used for the DVD bypass using a relay, cand i just use the radio 12v source wire, just tap into it, what should I do, thanks!!!
Also I'm using the system control out on the deh-p7000 5.1 surround unit for the amps and the seperate tv using fused relay.

So whats your question? Is it what to do with the adapter blue wire? If so then leave it hanging. It's for power antennas.

Yes, you can hook the blue wire up from the ANTENNA ADAPTER to your switched source.
