Against my better judgment I'll assume you're serious.

So the left headlight, when it's installed, does work?

Put away the chainsaw and pick up some proper electical tools like the lineman's pliers and a soldering iron.

You see on the back of the headlight assembly all the "pins"? And the plastic square on the ground? You've got to get those back in order.

From the rear the pins are

A B
C D

The holder needs to have those stubby sockets visible at about 30-40 seconds and again at the end reinstalled. The order is (again, from the REAR of the holder, like you were a socket going into the holder)

Grey/Green Brown
Yellow White

This means G/G = A (foglight); B = B (ground); Yellow = C (low), White = D (high).

That wiggly ground at 35 seconds is junk. Get a larger screw and snug that baby down tight to the fender wall. These connections MAY be enough to get the lights working but you really need to replace some of the wiring. I'd consider going as far back as the splices upstream of the headlight.

After that's ready we'll work on your turn signal.

And do everyone a favor and properly aim the headlights after they're back in. The factory sealed beams on these cars are weak enough, getting them aimed to point at the road properly is essential.
