I know that I need the 3 speed motor, link arm (off the motor) and a bushing(?) to change to a 3 speed. I have the whole linkage setup out of a 3 speed car too though not sure if I need all the linkage but probably be easier just to use that set up.
Correct, all the wiring is the same. I have a non rallye dash, so do I need a non rallye 3 speed ebody specific switch? And if I understand correctly, the non rallye is different then the rallye switch?
I would like to change over to a rally dash at some point as well.
You will need (in addition to what you listed) the 3 speed linkage as well as the correct switch, the standard wipers are just 2 speed and no variable speed function.
The wiring is different as well, not sure if you can ad/change the existing wires or if you need the correct harnesses.
I have been collecting all the parts to do the swap myself and just got a rallye dash harness so I didn't have to mess with the wiring differences (I am swapping the whole standard to rallye dash setup).
