XT25 Series: Conventional Hardwire Installation Guide
Before You Begin
The installation kit contains the XT25 GPS device, OBD-II to Hardwired harness, ring terminal, ground screw, star washer, cable ties, installation guide, and registration card.
Additional tools that you may need include a pen, dash panel removers, insulated crimpers, wire cutters, wire strippers, electrical tape, tamper seal, cordless drill, Phillips bit, razor blade/knife, and multimeter.
Installation Overview
The following steps provide an overview of the installation process:
- Install Preparation.
- Harness Installation.
- Install Accessory.
- Device Connections & Mounting.
- Verify and Secure Install.
1. Installation Preparation.
Locate the device, Hardwire harness, wire strippers, cable ties, wire cutter, registration card, pen and dash panel removers.
- Record the 15-digit serial number on your registration card.

- Remove the dashboard panels for harness installation and device mounting.
Note: The device will be mounted behind the dash cluster.
Connect the OBD-II to the Hardwired Adapter to the GPS device and secure the connection with a cable tie.
Remove 1 1/2-in (4 cm) of insulation from the harness White, Red, and Black wires, then twist the wire ends and cable tie all inline fuse holders.
2. Harness Installation.
Locate the multimeter, Hardwire harness, wire strippers, insulated crimpers, razor blade, electrical tape, star washer, ring terminal, ground screw, and cable ties.
Hardwire Harness
- Locate a vehicle wire which provides between 12 VDC (+) and 24 VDC (+) while the vehicle is On and running, and 0 VDC (+) when the key is in the Off and Accessory position. This will be the device’s Switch Source of power (Harness White Wire)
- Complete the following steps to poke and wrap the connection:
- Remove 1 in. (2.5 cm) of insulation from the vehicle wire identified and poke something nonconductive through the exposed wires to create a loop, then insert the exposed White wire strands into the loop.
- Squeeze the loop shut, and tightly wrap the bare wire around the exposed wire at least three times.
- Fold the wire back and generously wrap electrical tape around the connection, crossing over the insulation on both sides.
- Secure the connection with one cable tie directly over the wire-to-wire connection and another cable tie on a stress loop created about 1 in. (2.5 cm) away from the connection.
- Test for a vehicle wire that provides between 12 VDC (+) and 24 VDC (+) with the vehicle On, Off and Keys Removed. This will be the device’s Constant Source of power (Harness Red Wire).
- Complete the same poke and wrap steps mentioned above in Step 2.2: A-D, connecting the Red wire to the Constant Power Source.
- Locate a suitable location on the chassis to mount the ground wire.
- Fold and crimp to the ring terminal.
- Slip the star washer over the self-tapping screw first, then through the ring terminal.
- After confirming there is nothing behind the mounting location, screw the ring terminal to the chassis.
- Route the harness to the area behind the dash cluster.
5. Verify & Secure Installation.
- Text the Activation Code from Step 1.1 to ClearPathGPS at telephone number: (805) 695-2388.
- After you text your Activation Code to ClearPathGPS, you will receive a few text messages prompting you to reply with information about the vehicle. Respond to the prompts with the following:
- Vehicle Name: This is the vehicle label that you will see on the Map
- VIN (Vehicle Identification Number): This can be found on the vehicle’s registration and on the vehicle itself
- License Plate
- Current Odometer
- After sending the current odometer, turn on the vehicle’s engine and wait 30 seconds.
- Turn off the vehicle’s engine and wait 30 seconds.
- Text “Done” to (805) 695-2388. You should receive a text response stating: “Installation complete.”
- Upon completion, reassemble the vehicle’s dashboard, and give the registration card to your GPS administrator.
