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. 
Date Code R1 or Earlier

If dial illumination is NOT required, either wire harness can be used on any date code, if the YELLOW 
wire is NOT connected. 
 
Wire/Connector Assembly 
 
NOTE:  EG21 Series gage and EGS21 Series Swichgage movement and illumination 
require 12VDC to function.  For 24 or 32 volt systems, voltage converters are built into the 
electrical wire/connector assembly and supplied with instrument.   
Listed below are replacement part numbers for all wire/connector assemblies.  Voltage converter included for 24 
and 32 volt.  Specify part number when ordering.
