MAF Sensor

I have a 1991 cherokee limited, and I was wondering where the MAF sensor is located? Also, I was wondering which 2 wires lead to the MAF sensor? If anyone can help I would greatly appreciate it.

I don't believe it has a MAF sensor but rather a MAP sensor located at the throttle body.

No MAF sensor on any year 4.0
MAP sensor is on the firewall.

I did mean MAP. I don't know why I typed MAF. But there are 2 sensors going into the throttle bottle and I was wondering which was the MAP?

The MAP is up on the firewall with a flimsy delicate vacuum line running forward to a rubber plug in the throttle body, I think. It will run rich (black smoke) if that's busted or off. The tps and the iac are on the throttle body.
