according to what's on ebay:
All Black with white stripe wires should tie to Black ( neg or grd ). Red should tie to White with Black stripe (Brake). White should tie to Brown (Running). Blue should tie to Blue (Left Signal). Yellow should tie to L ( Right Signal ) ( lavender ? couldn't make out on drawing. It's the only wire left ).
