Hello all! I want to apologize in advance if this has been asked already, but I can’t seem to find any information about this on any forum or website. I recently had my factory cassette radio taken out of my grand Cherokee, and I noticed that there was a single yellow wire with a brown stripe and a white plug on it but I cannot find any information regarding what this wire is for. This does have the CD changer equipped and it works fine. I am just not sure what this one wire does. Any suggestions or help would be awesome. Thank you!
