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 connector 
with the grey latch connects to the sens or.  The single-row connector connects to 
the back of the gauge.  The locating tables on the single-row connector \
should 
be farthest from the  center of the gauge. 
 
 
RED - Connect  BOTH RED wires to a constant 12 volt power source utilizing a 5A fuse. 
 
BLACK – Connect  BOTH BLACK wires to a clean power ground. 
 
PINK - Connect to a switched 12 volt  power source utilizing a 5A fuse. 
 
GREY - Connect to instrument lighting circuit supply voltage. 
  
*WHITE - Connect to Lambda + Input. 
 
*BROWN - Connect to Lambda – input. (Must  be connected if Lambda + is used) 
 
*optional – only needed if using the  available differential analog output  
 
Wiring notes: 
  RED - When wired as shown above, the gauge will park the needle upon 
powering down.  Alternatively, both RED  wires can be connected to a switched, fused 
12 volt power source.  With  both RED wires and the PINK  wire connected to switched 
power, the needle will remain  at its current position upon powering down.  For both 
power connection methods, the  needle will rotate to the parked position before rotating 
to the value of the current operating condition upon powering up. 
  GREY – The GREY wire is used to control  the lighting intensity of the gauge.  
Maximum lighting intensity is  achieved when the GREY wire is  connected to 12 volts.  
Minimum lighting intensity is achieved when  the GREY wire is not connected.  The 
instrumentation illumination on  many vehicles is controlled by varying the supply voltage 
to the instrument panel light s.  When the GREY wire is c onnected to the instrument 
panel supply voltage, the int ensity of the gauge is controlle d by the dimmer switch on 
the dash. 
  WHITE – The WHITE wire should be c onnected to the Lambda + input on the 
EMS or the analog + input on a similar device. 
  BROWN – The BROWN wire should be connected to the Lambda – input o\
r the 
analog – input.  If the EMS  or similar device does not have a – input, the BROWN wire 
should be connected to a sensor ground.  If  no sensor ground is available, the BROWN 
wire should be connected to a power ground.   Note: The BROWN wire must be 
connected in order to get correct  readings from the analog output.  
 
  
						

							 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 sor must be installed after the 
turbo charger, if not, the pressure different ial will greatly affect the accuracy of 
the unit . For accurate readings, the sensor must be mounted before catalytic 
converters and/or auxiliary air pumps. To  prevent collection of liquids between the 
sensor housing and sensor element during the cold start phase, the installation angle 
should be inclined at least 10° from horizont al with the electrical connection upwards, 
see below.  (Figure 2)

Changing the Bezel 
 
The AEM UEGO 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, glass lens, and rubber spacer are all removable.  Reassemble 
the gauge as shown below in Figure 3.   Do not over tighten the bezel when 
reassembling the gauge.

							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.

Status Lights 
 
The AEM UEGO gauge has two status lights, see  Figure 4.  The status light on the left 
is on during sensor warm up.  The light will turn off once the sensor reaches its 
operating temperature, usually within  30 seconds.  During sensor warm up, AFR 
readings may not be accurate.  The status li ght on the right will flash if an error is 
detected.  The status  light will flash on and off a number  of times, followed by a short 
pause.  The error codes are listed below in Table 1.

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 information to a data 
logger or an engine management system like t he AEM EMS or F/IC.  The transfer 
function for the output  is listed below. 
 
AFR = 2.375(V) + 7.3125 
 
For example, if t he output is 2.0 Vdc, the AFR is 12.06:1 
2.375 * 2.0 + 7.3125 = 12.06

Notes 
 
The sensor contains a ceramic module an d should not be subject to mechanical or 
thermal shock or it may be damaged. The s ensor is not designed for operation on 
leaded fuels, doing so will dramat ically shorten sensor life. Long term running in the rich 
region (Lambda < 0.95) will shorten sensor li fe. High exhaust temperatures (over 850C) 
will shorten sensor life. Engi ne oil consumption at a rate greater than 1 quart per 1,000 
miles will shorten sensor life.  With the UEGO Sensor insta lled, do not run the engine 
without power applied to the gauge.
