I got my new iPod Nano in the car last night. I snapped a few pics during the process so hopefully it can help anyone else wishing to do the install.
The interface is a Peripheral interface. When I bought the interface it came with a short(12" Long) adapter cable for the Vette. Unfortunately I don't believe the Z06's have pre-run cables to the trunk. This wasn't a big deal for me as I just cut one end of the plug off(Keeping the end that plugs into the Peripheral unit) and hardwired it to the 2 port plugs found in the passenger kickpanel/footwell.
Step 1:
Take out your footwell panel and your passenger kick panel/door sill.
Step 2:
Locate the 2 port plugs that you need to tap into. Optionally you can buy a harness that actually plugs into these plugs but, I believe it's about $40 or so and then you are left with about a 10 ft. clump of wires and nowhere to run them.
You can solder or use what I call the poke and wrap method. Which is where you cut out about a 3/4" piece of insulation, poke the wire with a test light to open it and then thread the wire through, close it and wrap the wire around and tape it up.
Here is a pic of the 2 plugs you are looking for:
Use this as your guide as to what colors from the Peripheral harness go to what colors on the port plugs.
Plug 1:
White to Connector Brown+White
Red to Connector Green+White
Orange to Connector Black+White
Plug 2:
Blue to Black Connector thick Orange
Brown to Black Connector Black+White
Black (smaller gauge wire) to Connector Dark Green
Step 3:
Remove your ashtray.(Hopefully you smokers don't smoke in the Vette)

Take the plug that plugs the iPod into the interface and run it through the hole behind where the ashtray was. Peel back the carpet so you can see the wire and pull it through.
Step 4:
Find location for Peripheral interface. I mounted mine above the fat harness pictured below. It's a pretty tight fit but, I held it up with a few wire ties as well. Plug all your plugs into the unit before mounting. Making sure of course to wire tie all your wires nice and neatly and out of the way.
Step 5:
Double check all your connections and close everything up.
Step 6:
Plug in your iPod and enjoy
Half Open...
Fully Open...
Fully closed WITH iPod Nano inside!
iPod Nano in hand...
Keep in mind that the iPod Nano is
tiny. If you have a different iPod you will likely need to choose a different mounting location like the armrest, glove box, etc.
