12 volt trailer cable connections

Cable connections, often referred to as helical cables or "suzies," come in various configurations including 7-to-7 pin, 7-to-13 pin, and 13-to-13 pin options. The 13-pin variants are offered with two core sizes: an 8-core version suited for basic trailers with minimal lighting needs, and a full 13-core version designed for caravans and trailers requiring comprehensive lighting functionality.
