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.
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 EGT's (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.
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.

The sensor is not designed for operation on leaded fuels, doing so will dramatically shorten sensor life.
