A lot of the governors came with two wires and were used with electromatic clutch. There should be some faint markings AD is overdrive and EC is the clutch. If those can't be seen, the clutch wire (unused and just poke it out of danger if you don't need it) is the one coming out of a sort of raised enclosure toward the edge and the OD wire is the one attached to a terminal and exposed. You should be able to disconnect from the governor connector and ground the harness end. The solenoid should try to energize. If not, look for a black plastic connector in the loom between the governor and main harness. They were eliminated as a source of intermittent problems but some cars had them. If still no luck, would suspect the kickdown switch.

I know the governor is hard to access and Packard had a special wrench. There are some prior threads where one poster made one by cutting and bending an open end wrench and gave instructions.
