Please check notes in each part listing to ensure the Power Distribution Block Connector is correct for your 1999 GMC K1500 PICKUP with a 5.0L engine. ACDELCO, STANDARD MOTOR PRODUCTS, & AIRTEX / WELLS are competing brands, and each brand's Power Distribution Block Connector may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Power Distribution Block Connector fits only certain 1999 GMC K1500 PICKUP models.
Clicking a "More Info" link will display a picture and/or other details about that Power Distribution Block Connector in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Power Distribution Block 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 K1500 PICKUP 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 1999 GMC will not be lost if you switch.
