Second photo is the back of a NOS Ford Ammeter also with two terminals. The lower left gauge. The face of it is shown in a previous post and has the same face as the one you show.
Added a 1941-42 Truck wiring diagram showing the ammeter in series.

Here’s a photo of my spare instrument cluster. It has an Ampere meter but it is wired separately from the oil pressure meter - there is no bridge.
Now I need to study the various wiring diagrams to see if it can be wired in in my 1943 F15A which has the BATT meter (last photo).
