I'm l looking in the Big Blue Book which unfortunately does not list color codes.

3 wires go to the wiper switch
1 wire goes to the washer pedal
and your ground.

Oh wait a minute - if I turn a few more pages I get color coding:
Everything is a black wire with additional coding. Except the brown which is ground. Here is what the BBB says:

Assume black wire PLUS striping:
Striping:

violet/blue - from wiper switch terminal 1 to wiper motor terminal 1
violet/white - from wiper switch terminal 2 to wiper motor terminal 2
violet/green - from wiper switch terminal 3 to wiper motor terminal 3
violet/white - from foot pump terminal 2 to wiper motor terminal 2

That's what the book says. I assume violet = red in your case?
