Step 3 — Install the power harness
In a typical installation, the MP modem is connected to the
vehicle's battery with the power harness. The MP modem
supports a voltage range between 9 volts direct current (VDC)
and 36 VDC, and is designed for both 12 VDC and 24 VDC
vehicle electrical systems.
Note: Electrical installations are potentially dangerous and should be
performed by personnel thoroughly trained in safe electrical wiring
procedures for vehicles.
Power connector
The power harness connects to the MP modem with a Molex
connector.
Power connector (Molex) pinouts
The pinouts for the Molex connector on the power harness are:
White wire

Red wire

The battery (red) and ignition sense (white) wires in the power
