Wiper control switch went on my Evo 4... I found a used one for an Evo 5 and it looks the same but it's on Ebay and I can't really tell from the pics and description if it will work on an Evo 4. The seller isn't sure if it is compatible either. Would anyone know if the Evo 5 switch assembly would work/fit and Evo 4? Or if there is any way to find out?

Or if anyone has any recommendations on a place to get an Evo 4 wiper control switch, that would be great.

Thanks in advance for any advice
