Electronic Instrument Module
The Electronic Instrument Module (EIM) consists of a digital fuel gauge, a digital speedometer, and an electronic odometer. Within the EIM, all displays share common electronic circuitry (i.e. power supply, dimming control, and computer).
When ignition switch is in the "RUN" or "ACC" positions or the door handle is pulled, the EIM is illuminated at maximum display brightness and is operational. The Continental EIM is not interchangeable with the Mark VII EIM.
