EG21 and EGS21 Series Electric Gage and Swichgage® Installation
for Pressure, Temperature, Fuel Level, Voltmeter and Ammeter
IMPORTANT NOTICE FOR ALL EG21 ELECTRIC GAGES AND EGS21 ELECTRIC
SWICHGAGES FOR 24VDC AND 32VDC APPLICATIONS
A change in the dial illumination circuit has made it necessary to change the external wiring harness.
If you use the incorrect wiring harness, irreparable damage will occur to the gage mechanism.
The table below lists correct wire harness assemblies for units by manufacturing date. For date code
R1 (January 1996) or earlier (Q12, Q11, etc.) the wire harness can be identified by P/N and by
BLACK shrink tubing on the YELLOW wire. For date code R1 (February 1996) and later (R3, R4,
etc.) the wire harness can be identified by P/N and by RED shrink tubing on the YELLOW wire.

wire is NOT connected.
