Harness identification and application

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: The State of California currently prohibits Installing HRN-GS16K2, HRN-GS09K2, HRN-GR09K1, and HRN-BD16S5 in a manner that relocates the in-vehicle diagnostic connector. The following documents provide guidance on installing harnesses using a direct plugin installation method without relocating the data link connector:

Alternatively, GO devices can be installed directly into the OBDII port using an extension/conversion harness that plugs directly into the OBDII port or other emissions diagnostic data link connector port. For more information on Geotab harnesses and adapters, see Harness Identification and Application.

! IMPORTANT: For heavy-duty trucks, always use a vehicle-specific harness when offered by Geotab or the vehicle manufacturer (see Harness Assessment Cheat Sheet GUIDE V2.0 [PUB] and this document). Where a heavy-duty truck-specific harness is not offered by Geotab or the vehicle manufacturer, use the adapter harness (HRN-CG13S1) for any 16-pin (OBDII) installation method to avoid possible GO device damage.

✱ NOTE: If a longer length is required to facilitate installation, connect a straight harness to a T-harness or another straight harness — where indicated below. The total harness length must not exceed 2 meters (or 6.5 feet).

✱ NOTE: Regardless of the length, two T-harnesses CANNOT connect to each other. Connecting two T-harnesses, or any two harnesses that exceed 2 meters, compromises the integrity of the data and may cause issues with the vehicle’s Engine Control Unit (ECU).

! IMPORTANT: Some vehicles have multiple diagnostic connectors to choose from when installing a GO device. For further information to compare and contrast OBDII and RP1226, please visit the following link: https://gtb.page.link/hKF7.
