INSTALLATION 
 
1. Disconnect the negative battery cable. 
2. Secure the gauge in a 2 1/16th” (52MM) mounting hole with the supplied bracket. 
3. Plug the 8-wire power harness into the mating connector on the back of the 
gauge and connect the wires as shown in Figure 1.  Note: the locating tabs on 
the side of the connector should be nearest the center of the gauge. 
4. Connect the sensor cable to the gauge.  The locating tabs should be closest to 
the center of the gauge. 
5. Mount the...

 Thermocouple Mounting 
 
The thermocouple included in the kit comes with a stainless steel compression style 
mounting adapter.  The mounting adapter consists of three pieces:  compression nut, 
ferrule sleeve, threaded body.  The threaded body has 1/8” NPT male threads.  To 
install the sensor, the threaded body can either be threaded into a hole with mating 1/8” 
NPT threads, or welded to the pipe/manifold.   Remove the compression nut, ferrule 
sleeve, and thermocouple from the threaded body....

Changing the Bezel 
 
The AEM Analog EGT Gauge comes with the black bezel installed.  However, a silver 
bezel is also included in the gauge kit.  To change the bezel, orient the gauge so you 
are looking at the faceplate.  Rotate the bezel counter-clockwise to unscrew it from the 
gauge cup.  The bezel,  lens, and rubber spacer are all removable.  Reassemble the 
gauge as shown below in Figure 4.  Do not over tighten the bezel when 
reassembling the gauge....

Status Lights 
 
The AEM Analog EGT Gauge has one status light, see Figure 6.  The status light will 
flash whenever the sensor is disconnected.   
 
 
 
 
 
 
Analog Output 
 
The analog output from the AEM Analog EGT gauge is a linear dc voltage signal that 
varies from 0.5 Vdc at 0 Degrees Fahrenheit (-18 Degrees Celsius) to 4.5Vdc at 
1800 Degrees Fahrenheit (982 Degrees Celsius) over the operating range of the 
gauge.  The signal is used for sending information to a data logger or an engine...
