How do you install a breaking switch into a 1969 Mercury montego?

I have the switch brand new from Kragen but i dont know how to install it and I cant find it on the web. There was never a switch in it so i dont have anything to go by.

the brake light switch is at the top of the brake pedal under the dash, it will have a clip that holds a small pin that keeps the brake light switch in place, its not that hard to do , if you have a skinny small friend have them do it, as there is not alot of room under the dash
