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 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.  Using the supplied hose adapter, boost tee, vacuum hose, and zip ties, connect 
the sensor to a good engine manifold...

  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....

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.

Analog Output 
 
The analog output from the AEM Analog boost gauge is a linear dc voltage signal that 
varies from 0.5 Vdc at 30 inHg (-1 Bar) vacuum to 4.5 Vdc at 35 psi (2.4 Bar) boost 
over the operating range of the gauge.  The signal is used for sending information to a 
data...
