NT-V4

The USFT NT-V4 Install Guide

We recommend installation of your device by a professional installer.

Please verify that your device is activated prior to installation. When 
activating a unit, refer to the device MID# on the underside of the 
tracking device. (Reference Image A.)

The NT-V4 requires a standard 3-wire installation to operate effectively. 
Please familiarize yourself with the following wire colors and functions.

 

 
 The 

red

 wire (power) should be directly wired to a constant 7V - 32V power source found at the 

 

key source or fuse panel.

 
 The 

black

 wire (ground) should be securely fastened to a grounded screw or to chassis ground.

 
 The 

white

 wire (ignition) is the ignition event wire that is installed directly to the ignition wire. 

 

Ensure that power to the ignition wire is available ONLY when the vehicle ignition is turned on. All 

 

makes and models of vehicles are different - we recommend you make sure that you know your 

 

particular vehicle’s Constant and Ignition wires and their specific color(s) prior to installation.

 The 

green

,

 

brown

 and 

yellow

 wires (outputs) can be used to honk the vehicle’s horn, unlock its doors 

 

remote start the engine, and disable/enable the starter.

 The 

blue

orange

,

 

purple

, and 

grey

 

wires (input) can be used to monitor many functions such as PTO 

 

activity (Power Take Off), emergency lights, panic switch, etc or a specified input for the customer.

Step 2: Status LED Lights

After installing the unit, and prior to securing under the dash area, make sure 

the unit has a solid 

green

 light and a blinking 

orange

 light that goes solid for 1 

second, then repeats the pattern. See table on page 2 of this Installation Guide 
for troubleshooting when one or both does not occur.
