I do not have service information for your model, but I looked up the sensor connector for a 2.4L in a Sonata. They also use two black wires, but the twelve volt feed wire is pink. That one goes to terminal three of the three-terminal plug.
Holding the connector so the terminals are closest to you, and the wires are pointing away from you, put the locating tab on top. Now, the terminals are numbered "one", "two", and "three" from left to right.
Use an ohm meter to measure the continuity to ground for the two black wires. One will read very low, close to 0 ohms. That is the ground wire. If goes to terminal one.
Your brown wire should have twelve volts on it when the ignition switch is on. As I mentioned, that goes to terminal three. The remaining black wire is for the sensor's signal. It goes to the center terminal, number two.
