Detailed Description

Standard Ignition S-1477 is an emission control electrical connector used at the vapor canister purge valve. It is engineered as a female connector with an oval housing and female terminals to restore a dependable electrical interface where the original connector has failed, loosened, or become damaged. Standard Ignition draws on long-term electrical component development to address common failure points found in original equipment connectors.

This part cross-references AC Delco (e.g., 13355748, PT976) for the same application. It is a strong match for repair work on Chevrolet Silverado 2500 HD, GMC Yukon, and Cadillac XT5 models, along with many other GM vehicles listed in the fitment data. The S-1477 is a practical choice when replacing a vapor canister purge valve connector on GM emission control systems.

What It Helps Fix

Installation Notes and Tips

Verify connector shape, terminal count, and terminal gender before installation. Match the vehicle application to the listed fitment for Chevrolet, GMC, Buick, Cadillac, Pontiac, Saturn, and related GM platforms. Inspect the mating purge valve and wiring condition before connecting the new part. For best results, confirm pin alignment and secure the connector fully to maintain a stable electrical contact.
