1948 Fords should have a sender on each head and there should be a wire crossing from one sender to the other (one sender needs to have two areas to connect wires to it)

Early Ford gauges do not use resistance sending units; they use bi metallic senders as in the attached picture.

And if running a single one, it must be the one with single terminal.
