    I have removed my non-JBL head unit from my 08 DC. There are three harnesses connected to the back of the unit. The adapter harness package that I bought from Crutchfield only has 2 harnesses. Does anyone have a clue what the third harness powers? It has 5 wires on it - blue, gray, black, and 2 white wires. I know the other two harnesses power the front and rear speakers along with power, illumination, etc... Thanks for your thoughts in advance.
