That is the Air temp sensor. It will throw a check engine code 10. The wires that connect are usually green/wht and red/yellow, I think. Since the harness is chopped who knows? To pull the codes check under the glove box on the right side by the door for a two wire plug. Use a paper clip or wire to jump the two wires together. Then turn the key on and count the blinks of the check engine light. Long bink is first digit short blinks for the second digit. If there are only short blinks the code is only one digit long. Each failure code is separated by a 1-2 second pause.
