This wiring harness kit is aimed at owners and technicians working on Chevy Silverado, Avalanche, Suburban, Tahoe or GMC Sierra and Yukon vehicles that use a stand-alone electric fan control and have a 34-inch radiator. It’s ideal for those replacing a worn OEM harness, upgrading to a dedicated two-speed electric fan setup, or restoring proper fan control after engine or radiator work. If your vehicle’s radiator differs in width or the fan uses an integrated control module, verify fitment or seek an alternative harness tailored to your specific configuration.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this harness work with any radiator size?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This kit is designed for 34-inch wide radiators only.
