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 pressure port that has 1/8” NPT female 
threads.  Note: a small amount of thread sealant may...

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...

Status Lights 
 
The AEM Pressure gauge has two status lights, see Figure 4.  The status light on the 
left will flash if an out of range low voltage sensor error is detected.  The status light on 
the right will flash if an out of range high voltage sensor error is detected.  In either 
case, the needle will point straight downward to signify an error.  See Table 1 for 
corrective actions.

Analog Output 
 
The analog output from the AEM 100 PSI Pressure gauge is a linear dc voltage signal 
that varies from 0.5 Vdc at 0 psig (0 Bar) to 4.5 Vdc at 150 psig (10.3 Bar) 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 pressure units in PSI is listed below. 
 
Pressure (psi) = 37.5 x Voltage – 18.75  
 
The transfer function for pressure units in bar...
