I did install a variable speed wiper on one of my 71 Dusters that i had because I needed the extra room to install my six pack air cleaner. The wire harness is the same, you just need the switch and the wiper motor.

I see they make a reproduction wiring harness for a 2 speed motor but not a 3 speed .Is the correct plug in for a 3 speed motor part of a different harness?

So the 3 speed harness is not being reproduced? I don't see it listed in Year 1 or is it part of a main harness unlike the 2 speed which looks like it's seperate and plug directly into the bulkhead?

"The wire harness is the same, you just need the switch and the wiper motor."

You also need the 272 cam arm and the tan colored bushing. The black 2 speed bushing will not work as well as the cam arm from the 2 speed.
Typically 3 speed motors come with their harnesses already installed. They are not plug in type to the motor.

That's what I was trying to say

The underhood wiring varied A BUNCH depending on where the car was manufactured, I have been discovering all sorts of little wiring differences with Los Angeles built cars!

The problem I think I may have is somebody installed a 3 speed motor into this Duster and I think it originally was a 2 speed.How can I tell if they changed the linkage/bushings/etc to work with the 3 speed?If I find out they didn't change over anything,I'll just switch it back to a 2 speed.It never rains in MN any more anyways

The linkage and pivots stay the same.
The cam arm should a part number ending with 272 for a 3 speed.
The bushing on the cam arm should be tan colored for a 3 speed.
It is black for a 2 speed.
