Standard Color Code for Wiring a 4-Flat Connector


The wires coming from utility trailer are white, yellow/brown and green/brown. Do I split those wires and colour to colour??


Expert Reply:

Yes, you would just want to connect color to color when rewiring a replacement 4-way connector like the Hopkins Endurance Quick-Fix Replacement 4-Way Flat Trailer Connector item # HM48190

Brown-Tail/Running Lights
Green-Right Turn/Brake - Remember green has an R in it
Yellow-Left Turn/Brake - Remember yellow has an L in it

I have linked a diagram below.
