Off Road CAT Vehicle Harness
Geotab engine diagnostics port adapters for Geotab GPS tracking hardware:
The CAT vehicle harness allows a Geotab GPS tracking device to connect to some CAT off-road vehicles. Using this harness will not ensure you will get engine data from the vehicle – however, from our testing we have found that we can recover standard SAE J1939 engine data from many different models and years. We expect this to be about half the off-road CAT vehicles. For those vehicles that do not provide engine data it will at least provide power and ground, in addition to GPS.
