Expert Reply:
7-Way connectors like the # A7WCB that you referenced should be wired by function and not color. Since trailer manufacturers can sometimes use non-standard color wires for the taillight functions of their trailer it is best just to determine the function of each wire from your trailer's wiring and then wire it by function to the 7-way you end up getting.
What you can do to determine the function of each wire is use a 12 volt battery like a car battery and run a jumper wire from the positive post of the wire to the wires of the trailer and then wire it by function according to the diagram I attached.
