Wiring New 4-Way Connector on Trailer with 5 Wires  


What do color wires go to? I have on a boat trailer brown, white, yellow, brown with green, and brown with yellow. Brown and brown with green are attached to each other, and yellow and yellow with brown are attached to each other. I am trying to hook to 4 flat connector Reese Towpower 78115 Insta-Plug Trailer End Connector with LED Circuit.


Expert Reply:

The colors you mentioned are white for ground, yellow for left turn/stop, green for right turn/stop, brown for running light which means that brown with yellow is for the left side running light and brown with green is for right side running light.

I attached a help article on trailer wiring for you to check out as well.
