Heck, Denny, I didn't think I had much to offer!
I'll work on it. In the meantime, it is pretty simple.
Looking under the dash at the motor, I have three ports on the side and one that is approximately at the paddle swing axis of rotation. Starting at the most outboard port and working toward the paddle:
1 - Has a red cap on it, plugging it off right at the motor.
2 - Has a vacuum line connected, coming from under the carburetor as the vacuum supply side.
3 - Mine has a short stump of hose connected to it, with a plug in the end. I believe this ordinarily connects to a vacuum booster, which I do not have.
4 - The port by the paddle swing is connected to nothing. I thought this was the discharge side of the vacuum motor.
My vacuum wipers work just fine with this arrangement...to the extent that a 51+ year old vacuum wiper design and components work!
I hope this helps those in need.
Bill
