Guys i wrote a small article on how you can create a CD or AUX adapter cable for the business unit. Users with radios manufactured after sept 2002 can use the AUX option.

Users with versions prior to that date must use the CD adapter cable, but should also have a CD changer in the trunk.

Here is the attachment in PDF form.
Can you tell me what the resistors do? I found the capacitors but i'm having a little difficult time with the resistors of that value. are they necessary?
