2006 Honda Civic success on AUX install; now need antenna adapter and power and sound

[IndyAnne]

Thanks for the response to my other thread concerning the parts included in my order for the AUX installation into my Honda Civic 2006.

Now, I need to order an antenna adapter from the factory stereo (39101-SNA-A010-M1) to an after-market antenna

and, I need a wiring harness to connect to power, speakers, etc. from the factory stereo into after-market speakers and a 12-volt power source

Is there a diagram of the 2006 Honda Civic wiring harness connecting the factory radio to the car's speakers, battery, and switched power? I checked www.installdr.com but the only diagram I found there was for a 16-pin connector. My factory radio has a 20-pin connector and a 17-pin connector that I think might receive a harness for an amplifier, but I'm not sure.

Does the 20-pin connector contain the outgoing pins for speakers, grounds, ignition, battery?

Can you tell I am using this for an external purpose, not in a car? I am adapting it to a vintage Airstream travel trailer since the factory radio was replaced by an after-market stereo with iPod, bluetooth, USB, and 3.5mm inputs.

Any tips on correct parts to order from Autotoys.com?

I am not sure if I understand you correctly. But I believe you are trying to use the radio from a 2006 civic into another car and need the harness and adapter to do that

You will need this
http://www.autotoys.com/x/product.php?productid=10818

which adapts the antenna to a standard motorola plug.
You can use any aftermarket antenna then (which is standard motorola)

We sell windshield mount antennas and also hidden antennas with this plug, see http://www.autotoys.com/x/home.php?cat=712

then further, you are asking about the plug that goes into a 06 civic radio, if this is correct

See http://www.autotoys.com/x/product.php?productid=12019

This new harness will have leads out and ALL of the leads will be labeled on the back of the package
Example: power, left front right speaker + and -, etc
