Boat Trailer Wiring Diagram 4 Wire. 3/4 inch by 1 inch 6 way rectangle connectors right turn signal (green), left turn signal (yellow), taillight (brown), ground (white). Is there a way to make a quick disconnect power wire for winch on boat trailer;
I have a shorelander profile trailer that is having lighting issues. Match each coloured wire on the light to the same colour wire on the trailer and twist firmly. Yellow and green are for left and right turns and braking.
Use on a small motorcycle trailer, snowmobile trailer or utility trailer.
The installation should take less than one hour. Below is a simple wire diagram for a standard four wire light harness. You must check the trailer manual to see if the wiring is correct, but normally the white wire is called the ground wire, while the brown wire is used for tail lights. The standard four prong connector to connect the trailer to the tow vehicle is perfect for a simple trailer light system.
