Speaker Wire

My driver side door speaker is not working. I know for a fact it is the wire in the door jam that connects to the door wiring harness that is the cause of this. The problem is I don't know which wire that is so I was hoping someone could describe to me which wire it is. Thanks.

Here is a picture of which part of the wiring harness I am talking about.

how do you know that the wire in the door jam is the cause?

an easy way is to remove the door panel, locate the speaker wires. they will be specific colors. then simply find the same colored wires in the door jam.

i bet this site will have the answer to the wire color: http://www.3saudiofaq.com/.

Thanks for the help I managed to figure it out.
