This is a 5-to-4 wire trailer harness converter. This is made by Show Chrome and is designed to convert a 5-wire system that is standard on vehicles that have separate turn signals and brake lights to a 4-wire system that is standard on many trailers that use a single lamp for both turn signals and brake light functions. It comes with a flat 4-pin trailer plug and wiring instructions.   16-127 Item:   B16-127  Show Chrome
