Built from 16AWG conductors inside a durable PVC jacket, the kit is made to resist abrasion, oxidation and common chemicals while matching standard 4-way flat sockets. The harness is color-coded for straightforward connections and suits a wide range of trailers where a split left\/right taillight feed is needed.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Y-shape 5-wire layout help when rewiring a trailer?\u003c\/h3\u003e\n\u003cp\u003eThe Y-shaped split separates the taillight feed into dual brown wires so each side receives its own signal, avoiding daisy-chained connections.
