I know I'm supposed to be talking about the wiring in this section... but when I went to document the headlight wiring, this is what I found behind the driver side head light. Yuck!

I can't leave this alone! We're going to take a slight detour so I can restore the headlights.

Of course, the driver side headlight is toast, as is much of the hardware. Fortunately, I have the passenger side to use as an example. The outer chrome trim is held in place with a single sheet metal screw. Removing this screw makes it possible to remove the chrome and gain access to the inner hardware.

The headlight itself is held in place by a chrome retaining ring, which is held in place by 3 small screws. Removing these screws allows the ring to be removed, and the light to be pulled out of the support hardware.
