Installation Guide

• The ground wire is actually three ground wires joined together at the exposed end, giving the
appearance of being one wire.
About the sensor wiring connections (digital inputs)
The EAT device is capable of sensing voltage transitions of at least 6 volts on 12/24 volt systems and
requires 3mA current when voltage is present in the on phase.
The device uses a trigger wire/reference wire setup method for each sensor input. As such each input
requires two connections to complete each input.
The signal to be monitored should have two voltage states. One with no voltage (i.e. zero volts when
referenced to ground) and another that falls in the range from 6 to 24 volts.
For sensor inputs, use one of the methods below for trigger wire and reference wire color
connections.
If you are wiring for a positive trigger...
Use the solid color input wire for the positive trigger.
Use the striped color input wire for the reference wire/input
ground.
If you are wiring for a negative trigger...
Use the striped color input wire for the negative trigger.
Use the solid color input wire for the reference wire/+VDC
reference voltage.
Note: It is important that the voltage signal be tested to ensure it is continuously providing the necessary
voltage and current when in the “on” or “active” position.
The device harness includes two weather-proof fuse holders, each holding a 3A mini-blade replaceable
fuse. Therefore, there is no need to splice in any fuses during installation. Replacement fuses, if needed,
can be purchased from any auto parts store. The fuses are located on the device’s red VDC power wire
and white ignition wire.
