* Throttle Position Sensor (TPS): This is almost certainly one of the three-wire connectors. The TPS provides the engine control module (ECM) with information about the throttle plate's position, crucial for fuel injection and ignition timing. The three wires typically handle:
* Signal voltage: Provides a variable voltage to the ECM representing the throttle position.
* Ground: Provides a ground path for the signal circuit.
* 5-volt reference: A stable voltage reference for the sensor.
* Idle Air Control (IAC) Motor: The other three-wire connector is very likely for the IAC motor. This small motor controls the amount of air entering the engine at idle. The three wires typically control:
* Power: Provides power to the motor.
* Ground: Provides a ground path for the motor.
* Signal: Provides a signal from the ECM to control the motor's position.
Important Note: Without a wiring diagram specific to your year and engine, this is an educated guess. To be absolutely certain, you should consult a wiring diagram for your specific 1995 Dodge Ram 1500 V8 engine. A Haynes or Chilton repair manual for your vehicle would be an excellent resource. Incorrectly identifying these connectors could lead to damage to your vehicle's electrical system.
