This RU644T uses a female connector, 4 blade terminals, and a 12-volt configuration, so matching the original part is important for proper fitment. For 2008-2009 Jeep Liberty models, verify the vehicle is without automatic temperature control. For 2007-2009 Dodge Nitro applications, confirm the 4 blade terminal requirement.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eStandard states that this replacement part is manufactured with quality control maintained throughout the production process and is tested for performance and reliability.
