The cable uses thickened PVC sheathing over 16 AWG copper conductors and arrives with color-coded wires and a standard 4-way flat plug so you can connect turn signals, brakes, and running lights without guessing which conductor goes where. The Y-branch splits the taillight circuit into dual brown leads for simultaneous left and right lamp connections, simplifying rewiring on trailers with separate lamp circuits.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this harness make rewiring both taillights easier?\u003c\/h3\u003e\n\u003cp\u003eThe kit’s Y-shaped wiring splits the taillight circuit into two brown leads, so both left and right tail\/brake lamps can be wired from a single harness run.
