Almost all vehicle types
are supported, although older vehicles may have less engine data available. For
vehicles that do not have the standard OBDII connector, Geotab offers custom
harnesses that allow you to connect the device into the vehicle’s diagnostic
port. Geotab also provides a special 3-wire harness that is connected directly
to the vehicle battery for power and allows you to connect the GO device to vehicles
that do not have a diagnostic port.
