12 Pin to OBD1 OBD2 16 Pin Adapter Connector Cable for GM
I connected the new OBD I adapter to my OBD II meter and plugged it into my truck. All the door locks and back window locks will not stop locking and unlocking. So I disconnected the adapter and I tried it again to see if this was just a fluke and it was not. The package came with no directions so I connected the adapter just like I would my OBD II meter. If someone has directions I would be willing to give it another try.
