Without knowing what lights you actually have, I can only help with possibilities. I recommend connecting the ground wire to a battery and then touching each of the other wires to the positive terminal to see function.

It sounds like you will have two wires that will tie into each other for the same function. You most likely have one wire for the running lights, separate wires for the stop and turn function in case you have a trailer wired that way (which most aren't but some Motorhomes are) and then the ground wires. The turn and stop can most likely just be wired together. If there is a dual filament bulb then there is another possibility where the bright filament would be the brakes and turn and then the other two wires would be connected for running lights.
