Here's a good illustration that shows where the MAP sensor is.

Your '98, if it's like my '97, has two 02 sensors. The "upstream" sensor that controls the air-fuel mixture is just below the exhaust header, screwed into the pipe. The "downstream" 02 sensor that only monitors the catalytic converter for proper operation is screwed directly into the cat itself. The cat is located mid-Jeep, near the transfer case.
