CURT electrical products are designed to deliver unsurpassed levels of performance, reliability and durability. Our philosophy in electrical is the same as our philosophy for trailer hitches: we want to provide the perfect fit". We want plug-and-play products that offer easy installation and superior functionality. The use of surface mount technology (SMT) components is just one of the steps CURT has taken to achieve this goal. SMT components are the most up-to-date parts available for circuit designs, offering lower resistance, reduced heat generation and longer life cycles than more common, out-of-date, through-hole-mounted components. CURT applies SMT to a full line of tail light converters and to any custom vehicle-to-trailer wiring harnesses (also called T-connectors) with built-in converters."
