I got my avic coming from crutchfield in may, and I got the new metra DD from ebay. I believe crutchfield is sending my everything I need. the only thing I am unsure of, and would like to know beforehand is

 

A. where can I get the VSS wire?

 

B. and where can I get the illumination wire

 

My stereo is the value one, not the large screen, but rather the small single line of text one. Can anyone think of any pitfalls to avoid?
