Please check notes in each part listing to ensure the Turn Signal Relay Connector is correct for your 1993 GMC G3500 with a 5.7L engine. STANDARD MOTOR PRODUCTS & ACDELCO are competing brands, and each brand's Turn Signal Relay Connector may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Turn Signal Relay Connector fits only certain 1993 GMC G3500 models.
Clicking a "More Info" link will display a picture and/or other details about that Turn Signal Relay Connector in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Turn Signal Relay Connector, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Electrical-Connector parts, other GMC G3500 parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1993 GMC will not be lost if you switch.
