Need help with couple of unidentified (to me) wires

Thanks, found the terminal for the brake wire!

As for the brown wire....I suppose anything is possible as far as where the harness came from and what year. Most old cars have mysterious origins with some of their parts, that's for sure. I do have a brown with yellow wire coming from the switch on the transmission to the starter relay but it is unbroken; however it is the exact same color as the one that is cut.

Oh, and my washer wire is a solid brown wire with no yellow.
