Replacement for GM PT2782 Multi-Purpose Pigtail Made in USA 12-Month Warranty

Restore a damaged electrical connection without replacing an entire vehicle wiring harness with the Wholesale Sensors Replacement for GM PT2782 Multi-Purpose Pigtail. Made in the USA and engineered as a perfect OEM-style replacement, this 3-wire automotive connector pigtail is designed to meet or exceed original fit, form, and functional specifications for compatible General Motors applications.

The PT2782 is designed as a splice-in replacement connector. When the original connector housing, terminals, or short section of wiring becomes damaged, technicians can remove the defective connector and splice the replacement pigtail into the existing vehicle harness. This provides a practical repair for compatible sensor circuits while preserving the remainder of a functioning wiring harness.

Replacement for GM PT2782 and 13585316

The primary interchange numbers for this pigtail are:

ACDelco PT2782
GM 13585316

GM’s official parts catalog confirms that GM 13585316 corresponds to ACDelco PT2782. GM describes the original component as a Black Multi-Purpose Pigtail designed to be spliced into compatible vehicle wiring harnesses. GM Parts Store

A documented aftermarket cross-reference is:

Dorman 645-785 FinditParts

The Wholesale Sensors replacement is an aftermarket component and is not represented as a genuine GM or ACDelco part.

Always verify the original connector, terminal configuration, wiring diagram, and OE part number before installation.

3-Wire, 3-Terminal Connector Design

The original PT2782 uses a black oval connector housing with three wires and three terminals. GM specifies a male connector gender with female blade-pin terminals. The original pigtail measures approximately 8.5 inches overall. GM Parts Store

This configuration makes PT2782 useful for several GM electrical applications where the matching 3-terminal connector is specified.

Because GM identifies PT2782 as a multi-purpose pigtail, it should not be marketed as a connector for only one type of sensor.

For example, GM parts information documents 13585316 / PT2782 as a mating connector for a crankshaft position sensor in certain applications. Other GM catalog information documents the same PT2782 connector for a camshaft position sensor on a 2.4L application. PartSouq

Retail catalogs additionally categorize PT2782 under applications such as fuel tank pressure transducer and other sensor connector functions, reinforcing the importance of matching the connector to the exact vehicle and circuit. AutoZone

Saturn Sky 2007
Suzuki XL-7 2007-2008

The connector is also documented for select Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD applications. FinditParts

These vehicle listings do not mean PT2782 connects to the same component on every listed vehicle. Because it is a multi-purpose connector, its function can differ between applications.

Always verify PT2782 or GM 13585316 against the vehicle’s wiring diagram, VIN-specific parts information, or original connector before ordering.

Made in USA Construction

The Wholesale Sensors PT2782 replacement is Made in the USA and designed for dependable automotive electrical service.

The connector incorporates a durable molded housing, insulated lead wires, and secure electrical terminals. Protective insulation helps shield the conductors while the molded connector maintains alignment and retention at the mating component.

GM emphasizes protective outer coverings and color-coded leads as important characteristics of the original pigtail design. GM Parts Store

Each Wholesale Sensors replacement is rigorously tested for electrical continuity, terminal retention, connection integrity, wiring quality, and dependable electrical performance.

Repair Damaged Vehicle Wiring

Automotive connectors operate in demanding conditions. Engine heat, vibration, moisture, oil contamination, corrosion, repeated service, and age can eventually damage connector housings, terminals, or wiring.

A damaged sensor connector may produce symptoms such as intermittent sensor readings, loss of signal, poor electrical continuity, intermittent engine operation, warning lights, or diagnostic trouble codes associated with the affected circuit.

PT2782 allows the damaged connector and short section of wiring to be replaced without unnecessarily replacing the entire vehicle harness.

However, the pigtail should only be replaced after proper diagnosis. A trouble code identifying a sensor circuit does not automatically mean the connector is defective.

OBD-II Diagnostic Code Information

There is no single OBD-II code that PT2782 universally fixes.

This is important because PT2782 is a multi-purpose connector used on different electrical circuits depending on the vehicle.

For example, GM catalog information documents PT2782 as a mating connector for a crankshaft position sensor on certain engines, including an application with GM crankshaft position sensor 12596851 / ACDelco 213-3208. PartSouq

Other GM information documents PT2782 on a camshaft position sensor circuit. Nemiga Parts

Therefore, codes related to crankshaft, camshaft, fuel tank pressure, or another circuit should be diagnosed according to the exact vehicle’s service information. Do not replace the connector solely because a particular code is stored.

Inspect the sensor, connector, terminals, wiring, power supply, ground, reference voltage, signal circuit, and related control module as applicable.

Straightforward Splice-In Installation

GM describes its pigtail connectors as components that are ready to be spliced into the vehicle harness. GM Parts Store

Before installation, disconnect the battery according to the vehicle manufacturer’s service procedure. Locate the damaged connector and compare it with the replacement PT2782 before cutting any wires.

Document the original circuit positions and use the correct wiring diagram for the vehicle.

Do not rely on wire color alone when determining circuit position. Replacement pigtail wire colors may not always correspond directly to the vehicle-side harness colors. Match each wire according to its electrical circuit and terminal position.

Remove damaged or corroded wiring as necessary and make secure automotive-grade splices. Protect repaired connections against moisture, vibration, abrasion, and engine compartment heat.

Route the repaired harness away from exhaust components, belts, pulleys, fans, and sharp edges.

After installation, reconnect the battery, clear applicable diagnostic trouble codes if appropriate, and verify proper sensor signal and vehicle operation.
