I understand I need to buy the green yellow and blue connector it's just that pins 1-6 on my 20pin connector are already being used. I think they're being used by my speaker outputs cause I don't have a connector for my speakers. My question is what do I do cause I can't insert 5 and 6 into the 20pin connector caused spots 1-6 are taken up already.
You can always reinsert them in another yellow connector....but you have to make sure they are inserted in the exact same location....or it will make it difficult for you to return your car back to stock in the future.
Also...if you already have the preamp harness (the one in the pix with the RCA's and the yellow 6 pin connector)....then all you need to do is purchase the green 6 pin...the blue 8 pin.
Here...let me make it easy for you...here's what you need to order from the audi parts department:
Female 20 pin connector (split into three parts – yellow, green, blue)
- Yellow: Part# 4A0 972 643 (see picture 2j & 2o) - Used for: Pins #1-6 support the line-level output to the amplifier for Bose and none-Bose equipped vehicles.
- Green: Part# 4A0 972 643A (See picture 2f, 2o & 2d) – Used for: (in the Nav+), Pins #7-12 support telephone speaker + and – and some other functions.
- Blue: Part#4A0 972 643B (See picture 2f, 2k, 2o, 4d, 4e & 4f) – Used for: Pins #13-20 support the CD Changer, PhatBox MP3 player, Dension IceLink (for Apple iPod) or BlitzSafe Audio input device.

Also...if you borrow my pin extraction tools...you can complete this process in under an hour....if you try it with sewing needles...it could be a 4 hour project....trust me...I've done it both ways. Let me know when you are ready to do this...and drop me an email.

PS: Keep in mind...you will need to code your Nav+ for Bose...if you plan on running an aftermarket amp via the pre-amp connector. See my post on VAG settings.
