I had this all figured out once years ago, when I had to work on my first '72.
I'm not sure I will remember all of this still. This is one year ('72) only
stuff.
Of course one switch is for the backup lights. It closes when the MT is in R.
The second switch on the nose is the same, but for 4th gear. It connects to a
vacuum switch which enables the vacuum advance only in 4th gear. I generally
just bypass the vacuum switch and connect the vacuum advance directly to the
intake air distributor so that it's active at all times.
As for the third switch, the one on the side, I THINK it closed when the tranny
was in N, and I THINK it had something to do with the EGR. If I'm right, the
wire for that would have come from the small silver box to the left of the
engine that controlled the EGR.
