You might have been looking at a diagram for a truck with the "3-hole" warning light style cluster. Those have a different pin-out on the cluster connector.
The factory tach (when present) goes in the otherwise unused hole between the speedometer and fuel gauge. It is wired up with it's own separate harness so it doesn't connect into (or result in any changes to) the cluster connector pin-out that I posted earlier.

Yes, a Saginaw 3-speed with the factory column shifter should have the reverse light switch located on the column. I attached a pic of the reverse light switch in my 72 (which also has a Saginaw 3-speed) back in
post #11 of this thread.
As a somewhat related side note, there is an electrical switch on some Saginaw 3-speeds ... it's located on the side cover right near the 2nd/3rd shaft and is used for the TCS (Transmission Controlled Spark) emissions system (which is commonly disconnected).
