There is an OBD2 port under the drivers side dash. There is a small removable panel there. I have no clue which wires are what you're looking for, but that port is wired to the OBD2 ISO standard.
"Driving is like a narcotic, an addiction that can take over lives. It ruins people, breaks families apart, and even kills. Itís habit that needs to be fueled. Time, money, rationality, sweat, knuckle skin, and anyone who disapproves are of little importance to a driver, and are often overlooked. Hi, Iím Nelson, and Iím a drivaholic."
