2 speed to 3 speed wiper swap.

I did a 2 to 3 speed conversion and Kim was a great resource both in parts and advise, from what I remember you just need a new crank arm (pn#2822272) check with her about the large plastic bushing at that end I think it may be different also, the wiring is attached to the 3spd motor your 2spd has a removable harness that unplugs out of the main harness

Can't give a big enough Thumbs Up to her :thumrigh:
