Basically you would wire the colors white, yellow, and green color for color and then wire the brown green and brown yellow to the brown of the new plug and you'd be set. Wishbone 4-ways basically just split the signal for both sides of the trailer whereas standard 4-way just have the one wire that you'd then run to both sides.
