Heavy Duty Vehicles

Geotab Harnesses for your Heavy Duty Vehicle:

Most of the common heavy duty vehicles on today’s roads use either a 9-pin or 6-pin diagnostic port.

6-Pin Diagnostics Port

9-Pin Diagnostics Port

That being said, some heavy duty vehicles have special harness requirements or may have 14-pin ports which can provide more advanced engine information. We highly recommend you visually inspect the port of your vehicle. Please reach out to us with a photo of your vehicle’s diagnostic port and the make, model and year if you are unsure of the port type so that we can assist.

For any adapter or harness, please keep in mind that the GPS tracking unit must not be positioned where the signal will be completely blocked by metal.
