I have an Eclipse AVN 6600 left over from my old ride and I want to install it in my 2001 A4. I have a Metra kit on order.
Now here's my problem:
I need to find the speed sensor wire. On my old ride i tapped it off the OBD2 connector. Any info on what pin this is?
Also I need to find the reverse light (+) wire.
Thanks in advance for any help.

 

Wow what a resonse! Thanks alot guys!

 

VSS is white/ blue behind cluster you only need reverse if you are hooking up a camera and you can get it at the tail light or harness running to the rear
