Simple Installation

Simply plug the GO9 directly into your vehicle’s OBD II port or with an adapter where needed. No antenna or wire-splicing required. The device auto-calibrates to accommodate for installation in any orientation.

For heavy-duty trucks, always use a vehicle-specific harness when offered by Geotab or the vehicle manufacturer (see Harness Identification and Application [PUB] and North American Harness Assessment Cheat Sheet GUIDE V2.0 [PUB]) . 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.
