INSTALLATION 
 1.  Disconnect the negative battery cable. 
2.  Secure the gauge in a 2 1/16
th” (52MM) mounting hole with the supplied bracket. 
3.  Plug the 8-wire power harness into t he mating connector on the back of the 
gauge and connect the wires as shown in Fi gure 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...

 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 por t as all of these can cause the sensor to 
overheat.  On turbocharged engines the UEGO sen...

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 sm all precision style screwdriver.  The backlight switch is 
accessed through the small hol e in the back of the gauge.

Analog Output 
 
The analog output from the AEM Analog Wi deband Air/Fuel Ratio gauge is a linear dc 
voltage signal that varies from  0.5 Vdc at 8.5:1 AFR to 4.5Vdc at 18.0:1 AFR over the 
operating range of the gauge.  The signal is  used for sending...
