The MAP sensor is located forward and below the power brake booster. It is about the size of a grenade or an orange; shaped more like the grenade. One four wire connector and one vacuum line the size of a finger.

As I said before the air temp sensor is in the aircleaner airhorn (two wires). The coolant sensor is at the front of the motor along with the thermal time switch. The coolant sensor will have the same type connector at the air temp sensor. The thermal time switch is also two wires but has a different style connector.
