IMPORTANT: In California, relocating the in-vehicle diagnostic connector using HRN-GS16K2 as described in these instructions is currently prohibited. For direct plug-in installation guidance without relocation, refer to HRN-GS16K2 Installation – Direct Plug-In. Alternatively, use extension/conversion harnesses for direct GO device installation into the OBDII port or other emissions diagnostic data link connector ports. More information on Geotab harnesses and adapters can be found in Harness Identification and Application.
IMPORTANT: This universal harness kit HRN-GS16K2 is designed for most light-duty and medium-duty vehicles but is not intended for generic heavy-duty applications. For heavy-duty trucks, always prioritize vehicle-specific harnesses offered by Geotab or the vehicle manufacturer (see Harness Identification and Application [PUB] and Harness Assessment Cheat Sheet GUIDE V2.0 [PUB]). If a heavy-duty truck-specific harness isn’t available, use the adapter harness (HRN-CG13S1) with any 16-pin (OBDII) installation to prevent potential GO device damage.
The HRN-GS16K2 is a comprehensive OBDII 16-Pin T-harness kit equipped with twelve mounting brackets, designed to seamlessly connect a Geotab® GO device to a wide range of light and medium-duty vehicles across the globe. This universal Geotab Obd2 Harness kit, HRN-GS16K2, includes the mounting adapters detailed below, with numbered plastic adapters for straightforward identification (see “Adapters” section for specifics).

WARNING! Never install, configure, or remove any product while the vehicle is moving or in operation. All actions must be performed on securely parked, stationary vehicles. Servicing units during vehicle operation can lead to malfunctions or accidents, potentially causing death or serious injury.
WARNING! Securely fasten all in-vehicle devices and cabling, keeping them clear of all vehicle controls, including pedals. Regularly inspect devices and cabling to ensure secure attachment. Loose components can impede vehicle control, leading to unexpected acceleration, braking, or loss of control, potentially resulting in death or serious injury. Improperly fastened devices may detach during sudden vehicle movements, causing injury.
WARNING! If warning lights appear on the dashboard or the vehicle stalls or performs poorly after device installation, immediately shut off the engine, remove the device, and contact your reseller. Continuing to operate the vehicle with these symptoms can cause loss of control and serious injury.
WARNING! Keep in-vehicle devices free from debris, water, and environmental contaminants. Failure to do so may cause malfunctions or short-circuiting, leading to fire hazards, vehicle damage, or serious injury.
WARNING! Do not transfer devices to different vehicles after initial installation. Vehicle compatibility varies, and doing so can cause unexpected vehicle interactions, including power loss or engine shutdown during operation, poor vehicle performance, erratic behavior, and potential death, serious injury, or vehicle damage.
NOTICE: This product contains no user-serviceable parts. Configuration, servicing, and repairs must be performed by an authorized reseller or installer. Unauthorized servicing voids the product warranty.
