INSTALLATION
1. Disconnect the negative battery cable.
2. Find a suitable, in cab, mounting location and secure the X-WIFI module using
the supplied zip ties. Note: The X-WIFI is not weatherproof and should not be
mounted in the engine bay or exposed to outside elements
3. Plug the 8-pin power harness into the mating connector on the right side of the X-
WIFI and connect the wires as shown in Figure 1.
4. Mount the UEGO sensor as shown in figure 3.
5. Connect the sensor to the X-WIFI using the 6-wire sensor cable. The connector
with the grey latch connects to the sensor. The single-row connector connects to
the left side of the X-WIFI.
6. Mount the optional EGT sensor(s) as shown in Figure 6.
7. Slide the heat shrink tube over the sensor cable and connect the EGT to the
cable as shown below in Figure 7.
8. Connect the 3-pin EGT sensors cable(s) to the X-WIFI.
RED - Connect to a switched, fused (5A) 12 volt power source.
BLACK
– Connect to a clean power ground.
*BLUE - Connect to available 5 volt analog channel for EGT input.
*GREY - Connect to available 5 volt analog channel for EGT input.
*WHITE - Connect to Lambda + Input.
*BROWN - Connect to sensor ground. (Must be connected if the White, Grey, or blue
wire is used)
*optional
– only needed if using the available differential analog output
Wiring notes:
GREY
– The GREY wire should be connected to an available analog channel on the
EMS or similar device.
BLUE
– The BLUE wire should be connected to an available analog channel on the
EMS or similar device.
WHITE
– The WHITE wire should be connected 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 or 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 outputs.
