See if this helps. The plug is just behind the relay box. In this picture I pulled it up a bit and you can just see some white plugs in the boot.I have the seat off and cannot located the plug for the CD player.
If you bought a CD player for the Wing, the CD player should come with a cable of the appropriate length. You would need to drill a hole in the back of the trunk and run the cable from the plug behind the relay box into the well of the trunk.Thanks for the photo's.
I saw that plug, but assumed it could not be the correct one due to not reaching the trunk. How do I get it to the trunk area?
