Do anyone know what the White/Purple wire is or does? Located on a 2002 Town & Country radio harness. I connected every wire except the White/Purple, but the aftermarket Radio will not send sound to the speaker.

But, with the power still one, I would plug in the factory radio, hear the static, then disconnect the factory radio, connected the aftermarket radio, and magically, there's sound....


Please help, it's killing me.

Thank you,

 

 

not sure what system you have.
