What Is the APDTY 756326 Pigtail Connector Used For?
The APDTY 756326 is a universal 2-wire female pigtail connector designed to repair damaged or corroded electrical connections on a wide variety of automotive components. Unlike vehicle-specific harnesses, this connector is sold as a universal repair part that matches the physical connector shape and pin configuration used across multiple systems and manufacturers.
Common applications include:
- Fuel Injector Connector: Repairs broken or melted injector wiring on engines where the connector has failed due to heat or vibration
- A/C Compressor Clutch Connector: Restores power to the electromagnetic clutch that engages the compressor
- Door Jamb Switch Connector: Fixes interior dome light and door-ajar warning circuits
- Fluid Level Sensor Connector: Repairs connections to windshield washer fluid level sensors and other reservoir monitors
- Power Steering Pressure Switch Connector: Restores sensor signal for variable-assist steering systems
- Speaker Connector: Repairs door or dash speaker wiring in audio systems
This connector is sold as a repair pigtail only. You must match the physical connector to your existing component before ordering. Check the product images on the APDTY listing to confirm fitment to your application.
What Are the Symptoms of a Bad Wiring Connector?
When a 2-wire connector like the APDTY 756326 fails, symptoms depend on which component it serves. Common signs of connector failure include:
- Intermittent operation: Component works sometimes but cuts out over bumps or when wiring is moved
- Complete loss of function: Fuel injector stops firing, A/C clutch won't engage, door light stays on or won't turn on
- Check engine light: For fuel injector or sensor connectors, you may see codes for injector circuit malfunction or sensor open/short
- Visible damage: Melted plastic, corroded pins, broken locking tabs, or exposed copper wire at the connector
- High resistance: Corrosion inside the connector creates heat and voltage drop, causing poor component performance
Connector failure is often caused by heat exposure (especially near exhaust or engine components), moisture intrusion, vibration, or improper prior repairs. Replacing the damaged connector restores electrical continuity and prevents further circuit damage.
Which Vehicles Use the APDTY 756326 Connector?
The APDTY 756326 is a universal connector sold by physical match, not by specific vehicle year/make/model fitment. It replaces OE part numbers used by Chrysler, Dodge, Jeep, Ram, and General Motors vehicles, including:
- 05161919AB, 05161919AA, 5161919AB, 5161919AA (Chrysler/Dodge/Jeep/Ram)
- 89046836, 88988313, 89046838 (General Motors)
- 15306318 (General Motors)
- PT2160 (Aftermarket/OE cross-reference)
Important: APDTY does not provide a specific vehicle compatibility chart for this universal connector. You must visually match the connector shape, pin count, and terminal configuration to your existing component. Refer to the product images on the APDTY listing or consult your vehicle's wiring diagram to confirm compatibility before ordering.
This connector is most commonly found on Chrysler, Dodge, Jeep, Ram, and GM vehicles from the 1990s through 2010s, but physical match is the only reliable fitment method.

How Do You Install a Pigtail Wiring Connector?
Installing the APDTY 756326 pigtail connector requires basic electrical repair skills and tools. This is a permanent repair that restores factory wiring integrity. Follow these general steps:
- Disconnect the battery negative terminal to prevent short circuits and accidental airbag deployment (if working near SRS components).
- Cut away the damaged connector from the vehicle harness, leaving 3-4 inches of wire to work with.
- Strip 1/4 inch of insulation from each wire end on both the vehicle harness and the new pigtail connector.
- Crimp the wires together using weatherproof butt connectors or solder and heat-shrink tubing. Ensure correct wire-to-wire pairing (use a wiring diagram or match wire colors if available).
- Seal all connections with heat-shrink tubing or electrical tape to prevent moisture intrusion.
- Route and secure the new pigtail away from heat sources, moving parts, and sharp edges. Use zip ties or loom tape to protect the repair.
- Reconnect the battery and test component operation.
Safety Notes:
- If repairing fuel injector wiring, relieve fuel system pressure before starting work.
- Never splice wiring with twist-on wire nuts in automotive applications; use crimp connectors or solder only.
- If you are not confident in your wiring repair skills, consult a professional technician.
For fuel injector connector repairs, you may need to clear diagnostic trouble codes after installation and verify injector pulse with a test light or scan tool.
