What to monitor on this engine

Coolant temperature and RPM are practical first readings for this engine. Oil temperature and pressure are useful additions for warm-up and sustained engine load; a wired sensor provides a separate measurement route. An automatic-transmission temperature reading belongs to the automatic gearbox; it should not be labeled as a manual-gearbox reading.

Installation approach

Mount to fixed interior structure rather than removable roof or door hardware; secure the harness for rough-ground use. Fit the mount from your normal seating position before fixing it in place.

Connect the OBD-II adapter at the vehicle diagnostic connector and secure its cable along fixed trim. Leave the connector accessible for servicing. Follow the Flock user manual for gauge power, adapter setup and wired-sensor connections.
