I have a 2017 Jetta S so I have that head unit and recently bought a used head unit from a 2017 Jetta SEL w/o Nav, neither have a decal with the wiring diagram. I guess my only option is to remove the door panels and verify which pair of wires go to which speaker. I am pretty certain that on the speakers last I looked are embossed with which is.. Hello, I have a 2014 jetta s Im trying to install a sub and the head unit needs to be wired in. I cannot for the life of me find a wiring diagram with the right colors. The wires are all like brown and dark colors, not the normal wire colors.. Edit: the aftermarket head unit's wiring twisted onto the harness adapter's wiring.
