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: For heavy-duty trucks, use a vehicle-specific harness if available (see Harness Identification and Application [PUB] and North American Harness Assessment Cheat Sheet GUIDE V2.0 [PUB]). Never use a straight harness, i.e. HRN-BS16S4, HRN-BS16S4F, HRN-BS16S5, HRN-BD16S5, without the new adapter harness, HRN-CG13S1.
