As a followup I searched for under hood photos of 72 Tempests and noticed they did have rectangular wiper motors. That would explain the different wiring.

To sum it all up, The Yellow/Blk wire is on the end for rectangular motors and in the center for round motors.
Schematics will show the base model car which will be with a rectangular motor.

The next question for my education would be; Why does the Grand Prix schematic show a rectangular motor electrical connection? I'm assuming of course that all G bodies came with hidden wipers.

I thought at first that will be hard - I do not have a US number anymore, but there in my email inbox are several excellent, clear shots, thank you!

Your explanation makes the most sense here. As noted in another thread - everything is different between the two setups.

Further examination shows this 1968 GTO base motor:



Note how the 3 terminals are split 2-1 versus the round motor 3 in a row. I was puzzled why a 3 terminal round motor would have 2 connectors for 3 terminals...

Indymanjoe sent this to me, not sure if the connector is one or two piece... so maybe earlier round motors have 2-1 connectors while later are 3.



The 2 speed square wiper soldiered on till 1987, last seen in Chevettes and T1000's according to RA parts interchange.
