My OBD port was dead. After much investigation I found the power lead was "open" somewhere between the fuse box and the firewall(drivers side). The wiring bundle snakes across the front of the engine compartment making it difficult to trace the break. I cut the "+" lead behind the OBD port and added a female bullet connector(lower right pin #16 on the obd port-looking forward). A male bullet connector and wire and accessory plug goes to the accessory power outlet on the center console to power the OBD port. I keep the wire assembly in the center console with my code reader.
