The 30-2906-0 AQ1 Data Logger Harness Plug and Pin Kit is designed for applications 
requiring a custom harness or for applications not using the hard wired analog, 
analog/frequency, or switch-to-ground inputs.  The plug and pin kit harness comes with 
the necessary AEMnet, Power/Ground, RS232, USB, and CAN leads.  The pin locations 
for the analog, analog/frequency, and switch-to-ground inputs are not populated.  A bag 
of 20 terminals is...

INPUT SIGNALS 
 
Analog 1-4 are 0-5V analog inputs with optional pull-up resistor for RTD/Thermistor-
style sensor.  Examples: AEM gauges, MAP/pressure sensors, TPS/APP/shock 
travel/load cell sensors, analog MAF sensors, any 2 wire RTD or thermistor style temp 
sensor.  See “Using the AQ1 Data Logger” for more information on configuring Inputs 1-
4.  The corresponding wires in the harness for Analog 1-4 are Yellow and are labeled 
INPUT 1,...

Digital 1-3 are switched to ground digital inputs, 16.5 V MAX tolerance. 
Examples: Clutch/brake/cooling fan ground switch, nitrous solenoid ground or ground 
switch input to start/stop Logger (Ground activated input).  Figure 3 below shows wiring 
diagrams for an on/off activation switch and a nitrous solenoid.  The corresponding 
wires in the harness for Digital 1-3 are Brown and are labeled SW 1, SW 2, and SW 3.

RS 232 
 
The RS232 serial input on the AQ1 Data Logger is configurable to read either a 
standard NMEA GPS data stream or the data stream from an AEM EMS.  See “Using 
the AQ1 Data Logger” for more information on configuring the RS232 input.  The AQ1 
Data Logger harness comes with a male DB9 connector.  When connecting to an AEM 
EMS, the male DB9 connector plugs directly into the mating connector on the back of 
the AEM EMS.  The pinout for...

 To remove a terminal, carefully pry up on the retaining 
clip.  Be careful as the clips can break if bent too far. 
To add a new circuit, insert the terminal from the 
back as shown until it clicks into place 
Showing terminal fully seated.
