Please check notes in each part listing to ensure the Wiring Relay is correct for your 1993 GMC G3500 VAN RALLY with a 5.7L 350 OHV engine. STANDARD MOTOR PRODUCTS & ACDELCO are competing brands, and each brand's Wiring Relay may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Wiring Relay fits only certain 1993 GMC G3500 VAN RALLY models.

Clicking a "More Info" link will display a picture and/or other details about that Wiring Relay in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Wiring Relay, 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 on "Find More Parts", to find more Electrical-Switch & Relay parts, other GMC G3500 VAN RALLY parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button 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.
