Confirmation on wiper switch and misc.

I always refer wiper questions to two important places

The Passion for Mopars page

and the factory shop manual, which you can download, free, at MyMopar. Some of those manuals, including the '72, came from the guys on here

Once you match the switch to the motor, refer to section 8 of the shop manual, both the wiring diagrams and the sub-section in chapter 8 on wipers. Do a "wire by wire" matchup of the switch to motor wiring.
