I looked up your switch at Autozone (online)
Works very similar to my '77 Jeep CJ-5
The switch's plunger should be "IN" when the pedal is released (up).
You may have to slide/ adjust/ lock down the body of the switch in it's holder to make this happen against the "stop" (unable to grab a better word!).
I'm sending you a link to another answer I gave to someone else (See "my answers" in the link) I made a few pics in there too.
Keep us posted on progress.
Maybe it's just that simple!
