Pontiac GTO: Will NOT fit without modifications to the outside of actual OEM OBD2 port. since the shape of it is a tad different them most GM ports.
NOTE: Before installation, we strongly recommend assembling the unit off the vehicle first. This allows you to observe how the screws align and enter the unit smoothly. When it's time to install on the vehicle, you’ll have a clear feel for proper alignment and avoid stripping the outer portion of the lock.
INSTALL: Begin by placing the inner portion of the unit over the OBD2 port, ensuring that the bottom edge of the inner lock properly aligns with the tab located at the base of the OBD2 connector. Next, carefully fit the outer shell over the inner component (expect a snug fit during this step). Using the provided socket key along with an 8mm socket or wrench, secure the screws. Important: Avoid overtightening the screws to prevent damage to the unit or the OBD2 connector.
⚠️ Important: If screws are inserted at an angle, they will strip the lock’s outer shell and make removal nearly impossible once installed. If the screws don’t feel like they’re threading in easily, stop immediately! They should go almost as smoothly as they did during the off-vehicle test fit.
We will NOT replace stripped screws or units. Any damage caused by stripping is the responsibility of the installer and has nothing to do with the product. Remember ensure the screws are inserted straight.
