Dorman 645-163 Throttle Control Motor Connector

Dorman 645-163 Throttle Control Motor Connector

Dorman 645-163 is a throttle control motor connector pigtail built for clean electrical repairs and accessory installations. It uses weatherproof terminals and a locking tab to create a secure quick-disconnect connection on supported GM applications, including Chevrolet Cruze, Silverado, Tahoe, and GMC Sierra models.

Key Features

• Throttle control motor connector pigtail for electrical repair work
• Weatherproof terminals help maintain a sealed connection
• Locking tab supports a secure quick-disconnect fit
• 6-terminal, male connector design with female terminals
• 16-gauge wire construction with 415 mm overall length
• Direct replacement style for service on GM throttle control circuits

Product Details

This Dorman throttle control motor connector is built for vehicles that use a 6-way female connector with leads. The 415 mm lead length gives technicians room to make a clean splice and restore the connection without crowding the harness. Dorman 645-163 is a practical choice for repairing damaged connector bodies, heat-affected terminals, or brittle factory wiring on applications such as Chevrolet Malibu, GMC Acadia, and Cadillac CTS.

This part cross-references GM OE numbers 13504128 and 13584095 for the same application.

What It Helps Fix

• Broken or cracked throttle control motor connector housings
• Corroded or heat-damaged electrical terminals
• Intermittent throttle control signal loss caused by poor connector contact
• Harness damage at the connector end
• Failed quick-disconnect retention at the throttle control motor plug

Installation Notes

Verify connector style, terminal count, and wire routing before installation. Match the 6-way female-with-leads configuration to the vehicle harness, then splice and seal each circuit according to standard electrical repair practice. Confirm the locking tab engages fully after installation and inspect for proper terminal seating before returning the vehicle to service.

Quality Assurance

Built by Dorman for electrical repair applications, this connector is designed to restore a clean, serviceable connection on supported vehicles. It is listed for broad GM fitment across 2005-2021 applications, including Chevrolet, GMC, Buick, Cadillac, Pontiac, Saturn, Hummer, and select models such as Chevrolet Trax and Buick Encore.
