Confirmation on wiper switch and misc.

Although I will be looking for the correct switch, if the need arises is there a known way to make a jumper harness from my harness plug to the 2 speed switch to get basic operation?

Only way I know to attempt that is to dig into the shop manual and see if you can do so. EG about page 8-110 is a switch continuity chart. Maybe you can build on that. If you download the 73 manual, long about page 8-100 has some wiring diagrams

This is one area I'm "shakey." Everytime an issue comes up I have to dig in and figure it out. There are just too many "variables," no "3 speeds" about it LOL
