Default Pix wanted of wiper motor with harness plugged in

I have run into a baffling situation with the wipers. I have noted in my 1972 factory shop manual that the power wire going to the motor is in different positions by application. Note below that the A, F, and G bodies go to an end terminal, while the B's are in the center position.



This would be no big deal except some vendors sell motors with the same part number* for both variants and the plugs will easily fit either way - with possible smoke-filled consequences...

But the issue here is A bodies seemed to be wired both ways in the wild. Here a video shows a 1971 GTO undergoing wiper repair with the power feed in the center (1:40 minute mark).

My American Autowire install guide shows 1968-72 at the end as per shop manual.

Granted, these cars are all over 50 years old, so may have been modded a bit or a lot. I ask you to post pix of what you have, especially if it is very stock. Perhaps we can see where this goes.
