On every wiring diagram I have the matix box headings are so blurry that I can not read them. I came across a copy thay was printed in 1973 and here is a scan of the section in question.

Thank you.

Excellent Dan!

Interestingly, the wiper only shows ONE position and at that, it's one with what appears to be a resistance between 5 and 6. You would think that it would show three possible positions (if for the 73) or at least two for the 72 and earlier.

The clarity is excellent, and it confirms a few, heretofore, assumptions.

I am sure it is for a 72 or earlier, the original printing is 1972 and the book I have is the first reprint in 1973. The wiring diagram is titled HLS30 auto tranmission. It covers two pages so to get a good scan of the whole thing I will have to remove it from the book.
