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. To measure fuel pressure, thread the sensor into a suitable pressure port that 
has 1/8” NPT female threads.  Note: a small...

 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.

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 15 psig (1 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) = 3.75 x Voltage – 1.88  
 
The transfer function for pressure units in bar is...
