Well, we're on hold here for a bit. Datsun_Sky has been busy, but he will be following up with a pic and further info when he get's a chance.
I took a look at the EDM switch and had an idea. While the EDM switch should be plug and play we'd have the unused rear wiper control on the stalk. Either ignore it, or if you're weird about things like that as I am, swap the Maxima stalk onto it.
That said, MOJO what do you need from me so that I can get my hands on an EDM wiper switch?
