Ok!!! it's really a DATCON #102033. The meter records time. It runs from
battery power. I would like to wire it in some way so that it only operates
when the engine is running.

buy this oil pressure switch:

The low oil pressure warning buzzer and light shown on the schematic are
optional. They are not required for the Datcon hour meter function.
