How to Install Geotab’s HRN-GS09K2-A Universal 9-Pin Heavy-Duty T-Harness (Video Transcription)

9-Pin T-Harness installation:

  1. Refer to the installation insert included with the T-Harness kit, to identify the correct mounting adapter for your vehicle.
  2. To change the mounting adapter, unscrew the screw cap from the back of the connector and slide out of the way. Grip the wires at the back of the cartridge and remove the connector and adapter together. Slide the adapter off the connector.
  3. Slide the correct adapter over the end of the cartridge, keeping the square notch pointing towards the pins on the cartridge. Slide the connector onto the cartridge, lining up the installation slots. Slide the adapter over the connector, lining up the square notch on the adapter with the notch on the connector. Slide the screw cap up to the connector and tighten. Save the remaining adapters.
  4. Locate the diagnostic port usually found under the dashboard on the drivers side. With a screwdriver, remove the screws from the port to release the diagnostic connector from the plate.
  5. Connect one end of the 9-pin T-harness to the diagnostic connector that has just been removed. Zip tie the connection to make it secure.
  6. Connect the GO device to the 16-pin end of the harness tightly. You will hear 6 beeps along with a momentary flash from the red, blue and green LEDs. Turn on the ignition. The device will beep as each one of the LEDs lights up. Red indicates ignition detection, green indicates cell connection and blue indicates GPS latch. Wait for all three LEDs to come on.
  7. Secure the GO device to the harness with a zip tie. Secure the GO Device under the dash, then coil the harness and zip tie up under the dash to a permanent location. To ensure quality of data, the device must not move in any way under the dash.
  8. Take the remaining end of the 9-pin harness and place in the original port location and screw in place. The installation is complete.
