Wiring Questions for a 70

[Bowtie-Bri]

Hi Guys,
I'm in the process of putting all the wiring back where it came from on the firewall.
I have a brown wire coming thru a rubber grommet just below the wiper motor.
It doesn't have a connector on it and I'm not sure what its for.

I also have an orange wire in a harness that includes a purple wire and a thin red wire that has some type of insulated covering on it. The orange wire doesn't have a connector on it and I'd like to know what its for.

Any help would be greatly appreciated.
