Built with a heavier copper layer on copper-clad aluminum (CCA) conductors and a thick, flexible PVC jacket, the harness was engineered for towing environments where durability, straightforward installation, and consistent 12V signal performance matter.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this cable simplify a full trailer or RV rewire?\u003c\/h3\u003e\n\u003cp\u003eThe continuous 50-foot length eliminates the need for mid-run joins, reducing potential failure points and saving installation time.
