Please check notes in each part listing to ensure the Starter Switch Socket is correct for your 2003 PONTIAC BONNEVILLE with a 3.8L Supercharged engine. ACDELCO & STANDARD MOTOR PRODUCTS are competing brands, and each brand's Starter Switch Socket may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Starter Switch Socket fits only certain 2003 PONTIAC BONNEVILLE models.
Clicking a "More Info" link will display a picture and/or other details about that Starter Switch Socket in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Starter Switch Socket, 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 Ignition parts, other PONTIAC BONNEVILLE 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 2003 PONTIAC will not be lost if you switch.
