What are positions on 993 wiper switch?

[JoeMag]

Trying to figure out wiring for wiper for race car. I have cut pigtail that plugs into wiper motor...

1. What are the positions on the wiper switch?
2. Are last three, low medium high?
3. Is brown still used as ground? ...recall it was on my 82 930.

from neutral

the switch has 3 wiper speeds up, intermittent is down

2 pullback positions, 1 for a quick squirt of fluid & a few swipes and the second for a continuous stream of fluid & wiper action

1 push forward for headlight washers
