Smoking wire on 420G

As I was attending to something in the engind bay, after a short drive with the AC running, I saw smoke in the liw, early morning sun. It came frim the white wire attached to this odd part with 2 spring like components. Another 3-4 wires were also attached. What part is this related to? I guess either AC or electric windiw regulators (as another G without these US market extras, doesn’t have it). Cause and remedy??? [image] [image] [image]

Here’s the initial topic - is the black wire a ground wire? Is it supposed to go to ground?

A wiring diagram would be neat.
