WARNING! Use Geotab telematics devices only with Geotab-approved harnesses acquired from Geotab-authorized channels. Use of non-Geotab harnesses from unauthorized channels can cause serious safety risks, including fire, and can lead to serious personal injury and/or damage to the vehicle.

Important: For heavy-duty trucks, use a vehicle-specific harness if available (see Harness Identification and Application [PUB] and North American Harness Assessment Cheat Sheet GUIDE V2.0 [PUB]). Never use a straight harness, i.e. HRN-BS16S4, HRN-BS16S4F, HRN-BS16S5, HRN-BD16S5, without the new adapter harness, HRN-CG13S1.

Vehicle Assessment Instructions

  1. Request a complete vehicle list from the customer, which includes:
  1. VIN
  2. Manufacturer
  3. Model
  4. Year
  1. Use this Excel template to prepare a list of vehicles for harness assessment.
  1. Ensure that there is no missing information or incomplete entries.
  2. Normalize the manufacturer and model names.
  1. For example, change all variations of model name like F-150 and F150 in a single way.
  1. Use the Summary tab to get counts of each vehicle type.
  1. Use the compatibility table to determine which harnesses are required for each vehicle.

Vehicle Type Overview

Light-Duty Vehicles

All light-duty vehicles made in 1997 and afterwards will have a 16-pin OBD II port. They will be able to use the standard HRN-BS16S4 or HRN-BS16S4F harness or the HRN-GS16K2 universal T-harness. Review the compatibility table for any exceptions.

Heavy-Duty Trucks

Listed below are a number of common heavy-duty truck manufacturers:

  • International
  • Freightliner
  • Peterbilt
  • Kenworth
  • Sterling
  • Mack
  • Volvo
  • Isuzu
  • Mitsubishi (Fuso)

GO Rugged

Go Rugged requires specific harnesses for installation. For more detailed information about installation and harness types, please see the Vehicle Specific Installation Notes and the Harness Identification and Application document.

Finding the Diagnostic Port

There are several websites that can help you find the diagnostic port in your vehicle:

VIN Decoding

If you only have a VIN, there are plenty of online VIN decoding sites that you can use to retrieve the Make, Model and Year of a vehicle.

Harness Estimates

Note: Geotab does not guarantee that the following suggestions are 100% accurate. They are best guess and are considered to be estimates based on experience.
