Identifying Wire Color Functions on Trailer with 4-Way Wiring  


I have a trailer that im trying to get my lights to work. The trailer wires are green white yellow and brown the new wire has green green with brown white yellow and brown what gos where


Expert Reply:

The trailer wiring you have represents two very common color standards.

green will be right turn/stop
white is ground
yellow is left turn stop
brown is running light

The new wires that have brown and yellow or green are the running light circuit but designated to either side of the trailer. The green and brown is for the right side and yellow and brown is for the left side.
