This East Penn 4-conductor wire handles standard trailer signalling needs with colour-coded conductors for quick identification. Yellow, white, green, and brown wires run parallel-bonded together, then separate at the ends for connection to trailer plugs and vehicle connectors.

The 16-gauge stranded copper construction flexes easily during installation and maintains conductivity through years of use. Built to industry standards SAE J1128 and SAE J378, it’s suitable for RVs, marine applications, and utility trailers.
