Hi Everyone.  I just got my new Kenwood DDX812 and wanted some help verifying a few connections/questions if possible.  I have a 2002 honda accord coupe.  Any help is appreciated:

1. The parking sensor wire (lt. Grn.) needs to receive a ground in order for the DVD to work, correct?

2. The remote sensor wire (lt. Blue/yellow) can just be taped off until needed?

3. The mute wire (brown) can be left disconnected since the radio has built-in Bluetooth I plan on using?

4. I connect the dimmer wire (orange/white) from the kenwood to my harness's dimmer (orange/white) wire and can leave the harness's illumination wire (orange) unused?

5.  What is the difference between the Kenwood's Power Control wire (blue) and it's External Amplifier Control wire (pink/black)?

6. Can I connect the Kenwood's Reverse Sensor wire (purple/white) now to ease camera installation later even if I don't have a camera yet?  Where is the reverse wire on the Hondas and what color whould I look for?

Thanks so much for your time and any help you can give.  I can't wait to get this installed!
