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. Mount the sensor as shown in figure 2. 
5.  Connect the sensor to the gauge using the 6-wire sensor cable.  The connector 
with...

 Sensor Mounting 
 
A weld-in M18 X 1.5 boss is supplied for sensor installation. Mount the O2 sensor in the 
exhaust system at least 18 inches downstream from the exhaust port. If you anticipate 
high EGTs (over 800C), run a turbocharger, run at high RPM for extended periods of 
time or plan on running leaded race fuel then you must mount the sensor at least 36 
inches or more downstream of the exhaust port as all of these can cause the sensor to 
overheat. On turbocharged engines the UEGO...

Backlighting 
 
The Analog Wideband UEGO Gauge has 7 different backlight colors available to the 
end user, which closely match some of the more common factory dash panels: white, 
blue, green, red, orange, light blue, and aqua.   To change the backlight color, rotate the 
backlighting switch using a small precision style screwdriver.  The backlight switch is 
accessed through the small hole in the back of the gauge. 
 
 
 
 
Status Lights 
 
The AEM UEGO gauge has two status lights, see Figure...

Analog Output 
 
The analog output from the AEM E85 Analog Wideband Air/Fuel Ratio gauge is a linear 
dc voltage signal that varies from 0.5 Vdc at 5.6:1 AFR E85 to 4.5Vdc at 11.9:1 AFR 
E85 over the operating range of the gauge.  The signal is used for sending...
