Go Rugged 3-wire Harness


Can I use a 3-wire harness with the Go Rugged device in order to track engine hours on a vehicle without a diagnostic port? If so, what harness/hardware do I need to order?

This will work, however since it is a three-wire install it will not read engine hours from the engine itself; it will only track the amount of time that ignition is on after the device is installed. If you have an estimate for the current engine hours, you can input that on the MyGeotab UI (under Vehicles -> Select the vehicle -> input the values for engine hours), and it will start incrementing from that point onwards.

For a three-wire install, you would need to order harness HRN-CWO3S3.
