In regards to the Mighty Cord 7-Way RV-Style Trailer Connector part # A10-7W6, the most common mistake people make is that they try to match colors for installation which you just can't do. The trailer connector has seven wires, each of which with a certain function. Odds are, the tail lights you are trying to install have different color wires so you need to match function to function, not color to color. I have attached a list of each function for the above trailer connector below.

Yellow: Auxiliary or Reverse Lights
Green: Tail Lights
Brown: Right Turn and Brake Lights
Blue: Electric Brakes
Black: 12V Battery Charge
Red: Left Turn and Brake Lights
White: Ground
