➢
Connect Red wire of the ACUTE140 device power cable to the (+) Red cable at the vehicle
ignition input by removing the small portion of the PVC skin at least 2-Inch away from the
ignition switch (If already removed the skin for testing the voltage, use the same)
➢
Connect the Black wire of the ACUTE140 device power cable to the GND by connecting
the wire to the (-) terminal of the vehicle battery or to the point where GND wire of any of
the other accessories of the vehicle is connected and ensure that the connection is very
Firm/Tight.
➢
For all vehicles other than cars and SUVs, it is highly recommended to connect the (+) and
(-) of the device directly to the vehicle battery.

Connection to Ignition Output in the Vehicle
➢
Take each wire other than the (+) wire connecting the ignition switch assembly and look
for a metal conductor/ connector pin of the wire at the switch end, if not found remove a
small portion of the PVC skin away from the switch end .
➢
Keep the Ignition Switch in OFF position and follow the switch below
➢
Firmly hold the Red probe of the multimeter at the skinned portion of each of the wire one
by- one and black probe of the multimeter to the GND (- terminal of the vehicle battery or
any screw /Bolt directly connected to metal body of the vehicle) and measure the voltage.
The voltage must be ZERO when the Ignition is in OFF position.
➢
Keep the ignition switch in accessories position and follow the step below.
➢
Firmly hold the Red probe of the multimeter at the skinned portion of each of the wire one
by- one and black probe of the multimeter to the GND (- terminal of the vehicle battery or

voltage. The voltage must be equal to the battery voltage when the ignition is in
accessories position at least one wire shows ZERO voltage when the ignition is
in accessories position.
➢
Keep the Ignition switch in ON position and follow the steps below
➢
Take the wires that showed ZERO volts when the ignition at accessories position, firmly
hold the Red probe of the multimeter at the skinned portion of the wire and Black probe
of the multimeter to the GND (- terminal of the vehicle battery or any screw/ bolt directly
connected to metal body of the vehicle) and measure the voltage. The voltage must be
equal to the battery voltage when the Ignition is in ON position. Connect the ORANGE
wire of device wire cable to that wire it shows ZERO when the ignition switch is at
