Compatible GM Vehicles

The GM 13504128 replacement throttle actuator connector is intended for select General Motors vehicles requiring this original connector configuration.

Potential applications include compatible:

• Chevrolet vehicles
• GMC trucks and SUVs
• Buick vehicles
• Cadillac vehicles

Compatibility depends on the vehicle’s specific model, production year, engine configuration, electronic throttle body assembly, and original wiring connector.

Before purchasing, verify the OEM part number using the vehicle VIN, manufacturer parts catalog, or service manual.

Compare the connector housing, terminal arrangement, locking mechanism, and wiring configuration with the original component.

This replacement should not be considered universal across all GM electronic throttle bodies.

Electronic Throttle Actuator Connector Function

Modern electronic throttle control systems regulate engine airflow using an electronically controlled throttle body.

The engine control module monitors driver input and operating conditions to determine the required throttle position.

Electrical signals travel between the engine control system and the throttle body through the vehicle wiring harness and throttle actuator connector.

A damaged connector may interrupt electrical communication, produce intermittent throttle signals, or interfere with normal electronic throttle operation.

Replacing a confirmed defective connector pigtail may help restore proper electrical continuity and throttle actuator communication.

Made in USA Automotive Wiring Harness

The Wholesale Sensors GM 13504128 throttle actuator pigtail is manufactured in the USA for compatible automotive electrical repair applications.

The replacement connector and attached wiring allow technicians to repair damaged throttle actuator connections without replacing the entire engine wiring harness.

Proper terminal engagement, secure wiring connections, suitable insulation, and correct installation are essential for dependable electrical performance.

Before installation, compare the replacement pigtail with the original connector and confirm the correct wiring arrangement.

Helps Resolve Common Throttle Actuator Connection Problems

A damaged throttle actuator connector may contribute to:

• Illuminated Check Engine Light
• Reduced engine power warnings
• Intermittent throttle response
• Delayed accelerator response
• Rough or unstable engine idle
• Electronic throttle control warnings
• Intermittent electrical connections
• Corroded or damaged connector terminals
• Throttle actuator circuit faults
• Poor electrical continuity at the throttle body

Replacing the connector may help resolve these problems when damaged wiring or poor terminal contact is the confirmed cause.

Similar symptoms can result from a defective throttle body, accelerator pedal position sensor, damaged wiring elsewhere in the circuit, or engine control system faults.

Related OBD-II Diagnostic Trouble Codes

Depending on the vehicle’s electronic throttle control system, damaged throttle actuator wiring may contribute to:

• P2100: Throttle Actuator Control Motor Circuit/Open
• P2101: Throttle Actuator Control Motor Circuit Range/Performance
• P2102: Throttle Actuator Control Motor Circuit Low
• P2103: Throttle Actuator Control Motor Circuit High
• P2119: Throttle Actuator Control Throttle Body Range/Performance
• P2135: Throttle/Pedal Position Sensor Voltage Correlation

These codes do not automatically indicate a defective connector pigtail.

A qualified technician should inspect the electronic throttle body, electrical connector, wiring, and related components before replacement.

Installation and Replacement Instructions

Turn off the ignition and follow the vehicle manufacturer’s service procedures before beginning repairs.

Disconnect the battery when required by the manufacturer’s recommended procedure.

Locate the original throttle actuator connector on the electronic throttle body assembly.

Inspect the connector housing, locking mechanism, terminals, and attached wiring for corrosion, damage, or loose connections.

Compare the replacement GM 13504128 pigtail with the original component to verify the correct connector configuration.

Remove the damaged connector and prepare the vehicle wiring according to approved automotive electrical repair procedures.

Connect the replacement pigtail using appropriate automotive wiring repair methods.

Match each wire to its correct circuit function using the factory wiring diagram rather than relying on wire color alone.

Insulate and secure the repaired connections to protect against moisture, vibration, heat, and engine compartment conditions.

After installation, verify proper electronic throttle operation using the manufacturer’s diagnostic procedures.

Some vehicles may require throttle position or idle relearn procedures after electronic throttle system repairs.

Professional installation by a qualified automotive technician is recommended.
