INSTALLATION

1. Disconnect the negative battery cable.

2. Find a suitable in-cab or under hood mounting location for the Inline UEGO
controller, away from any direct heat or water sources and shielded from the
elements. Secure the controller using the supplied zip ties as shown in Figure 3.

3. Connect the flying lead wires as shown in Figure 1.

4. Mount the UEGO sensor as shown in figure 2.

5. Plug the UEGO sensor connector on the UEGO controller into the mating
connector on the UEGO sensor.

UEGO Sensor Mounting
A weld-in UEGO bung is supplied for sensor installation. Mount the UEGO 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. On turbocharged engines the UEGO sensor must be installed after the

turbo charger, if not, the pressure differential 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 horizontal with the electrical connection upwards,
see Figure 2.

Indicator Lights
The Inline Wideband UEGO Controller has two indicator lights, see Figure 4. Both the

ready light and the status light flash during sensor warm up. Once the sensor reaches
operating temperature, usually within 30 seconds, the status light will turn off and the
ready light will remain on solid. During sensor warm up, AFR readings may not be
accurate. The status light will also flash if a sensor 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.
