    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. Thread the sensor into a suitable temperature port that has 1/8” NPT female 
    threads.  Note: a small amount of thread sealant may be used. 
    5.  Connect the sensor to the gauge using the 2-wire sensor cable.  The single-row, 
    3-position connector connects to the back of the gauge.  The locating tabs on the  
    connector should be nearest the center of the gauge. 
    6. Reconnect the negative battery cable. 
     
    RED (Power) - Connect to a constant 12 volt power source utilizing a 5A fuse. 
     
    BLACK (Ground) – Connect to a clean power ground. 
     
    PINK (Switched Power) – Connect to a switched 12 volt power source utilizing a 5A 
    fuse.   
     
    GREY (Light Intensity) - Connect to instrument lighting circuit supply voltage. 
      
    *WHITE (Analog Output) - Connect to Analog + Input. 
     
    *BROWN (Analog Ground) - Connect to Analog – input. (Must be connected if Analog + 
    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 against the 
    needle stop upon powering down.  Alternatively, the RED wire can be connected to the 
    same location as the PINK wire.  With the RED wire and the PINK wire connected to the 
    same 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 lights.  When the GREY wire is connected to the instrument 
    panel supply voltage, the intensity of the gauge is controlled by the dimmer switch on 
    the dash. 
     WHITE – The WHITE wire should be connected to the Analog + input on the 
    AEM EMS or the analog + input on a similar device. 
     BROWN – The BROWN wire should be connected to 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.

    Changing the Bezel and Faceplate 
     
    The gauge kit comes with the black bezel and black faceplate installed.  However, the 
    kit also comes with a silver bezel and multiple faceplates.  Instructions on how to 
    change the faceplate are included in the kit on a separate sheet of paper.  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, lens, and rubber 
    spacer are all removable.  Reassemble the gauge as shown below in Figure 3.  Note: 
    When reassembling the gauge, it may be necessary to apply a light amount of pressure 
    on the lens and spacer to keep the faceplate from rotating when reinstalling the bezel.   
    Do not over tighten the bezel when reassembling the gauge.  
     
     
     
     
     
     
     
     
    Backlighting 
     
    The AEM Boost 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.

    Status Lights 
     
    The AEM Temperature gauge has two status lights, see Figure 4.  The status light on 
    the left will turn on solid if the temperature is less than 100°F (40°C).  The status light on 
    the right will flash if the temperature exceeds 300°F (148°C).   Both status lights will 
    flash if the sensor is disconnected.  The needle will point straight downward if the 
    temperature exceeds 300°F (148°C) or the sensor is disconnected.  See Table 1 for a 
    description of the conditions.

    Analog Output 
     
    The analog output from the AEM Temperature gauge is a linear dc voltage signal that 
    varies from 0.5 Vdc at 100°F (40°C) to 4.5 Vdc at 300°F (148°C) over the operating 
    range of the gauge.  The signal is used for sending information to a data logger or an 
    engine management system like the AEM EMS or F/IC.  The transfer function for 
    temperature in degrees Fahrenheit is listed below. 
     
    Temperature (Fahrenheit) = 50 x Voltage + 75  
     
    The transfer function for temperature in degrees Celsius is listed below.   
     
    Temperature (Celsius) = 27 x Voltage + 26.5 
     
    A list of output voltages and corresponding temperatures is shown below in Table 1.
