Trailer Light Converter (5 to 4 module)
If your trailer has only two lights on the rear then it is a 4 wire setup (has combined brake and turn signals), you also need our made in the USA converter.
How do you tell if you need it? Look at the wiring plug on your trailer - does it only have 4 wires? If yes, then you will need a converter.
If you have 4 lights on the rear of the trailer, then you do not need a converter.
Installation simply requires you to plug it in-between the Sub-Harness and the Isolator and then connect one wire to ground.
Going to a 4 wire setup is completely reversible by simply unplugging the module to revert to a 5 wire system.
Adding the converter only utilizes 3 of the 4 circuits in the isolator - the design allows the 4th circuit to power an accessory.
Our converter will work with LED lights since it is active electronics.
