, the other may be for tbe emergency brake switch

That is exactly what it is for. There is a door switch like switch on the e-brake and it has a single round connector.

Next is the other pick with a wire with a piggy back on it?

Might be wire to emergency flasher switch, and the piggy back would go to the turn signal switch.

It would be helpful to know:

What year
What car
What modifications
