Looks like you have a round 4-way connector in the picture you submitted. The colors you mentioned aren't totally a match for standard colors but they are close. Normally the colors are:

White - Ground Return
Green - Right Turn and Brake Lights
Yellow/Red - Left Turn and Brake Lights
Brown - Tail Lights

You'll need to wire by function instead of color since yours aren't a total match.

I have attached a photo that shows typical wiring for a 4-way round connector.
