Please check notes in each part listing to ensure the Oil Pressure Sender / Switch Connector is correct for your 1991 CADILLAC ALLANTE with a 4.5L engine. STANDARD MOTOR PRODUCTS, AIRTEX / WELLS, & ACDELCO are competing brands, and each brand's Oil Pressure Sender / Switch Connector may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Oil Pressure Sender / Switch Connector fits only certain 1991 CADILLAC ALLANTE models.
Clicking a "More Info" link will display a picture and/or other details about that Oil Pressure Sender / Switch Connector in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Oil Pressure Sender / Switch 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 CADILLAC ALLANTE 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 1991 CADILLAC will not be lost if you switch.
