Need some electrical help with my ‘68 Plymouth Valiant 100

And one other thing. I don't think this was mentioned yet.

If your car is a '68, then it came from the factory with left-handed lug nuts on the left (driver's) side of the car.

That means they come off clockwise.

You can tell by looking at the ends of the studs: The ones on the left will have an "L" stamped into them. (You may need to use a wire brush to see).

If you turn them clockwise, and you are persistent, you will have a bad day.
