I have one from an 02 P5. It will work in the sedan and you'll even be able to amaze your friends with your new found rear wiper capabilities.
If interested, I'll do $20 shipped and can get a pic posted once I get home.
I have one, can do like $15 shipped, or if you want the switch with the white plastic piece it attaches to and the directional and headlight switch i can do $25shipped. Let me know
