1998 Chevrolet Monte Carlo Z34 V6 3.8L CRANKSHAFT POSITION SENSOR -- Blade type; With a 2-prong male terminal:

You'll need to pull the passenger front wheel, remove the wheel well cover. This will expose the damper pulley on the crankshaft. Remove damper pulley, remove plastic engine cover. Look inside you will see the sensor. Be sure if you replace it to install the new one exactly the same as the old one was.
