I have a 2008 Lincoln MKZ with the standard factory radio. I went to a junkyard and found a cool factory lincoln radio which was touch screen and carried a navigation system. After taking out my base model radio and installing the new cooled looking radio I noticed that most of the wires plugged right in! The radio works great... other than the fact that I have no control of the volume. After going back to the parts yard I noticed the other vehicle having one extra plug that my car did not possess. This plug consists of two solid gray wires, one solid purple wire, and a yellow wire with a purple line... could this 4 wire plug be the issue of no volume control?
Everything else seems to work great.
Not a knob or command issue as the volume does appear to be giving command on the screen. The audible sounds remains at a constant high volume.
Any ideas?!
Anybody have some sort of wiring diagram I could follow to possibly figure out where this extra plug is supposed to go?!
Thanks,
Dan
