NAMZ, Trailer Isolator

With 6 position Molex plug. A trailer requires power for lighting. The Trailor Isolator is Plug & Play and sends power, used for the trailer, directly from the battery to trailer through a bank of 4 relays. The Trailer Isolator gets the signal from brakes, running light & turn signals. It therefore isolates the factory turn signal module from trailer power draw, preventing a costly premature module failure. Fits: > 14-20 FLTR Road King & Police models
