It's highly unlikely that you will find the correct adapter for your bike, you will need to remove the old headlight connector and solder in the new connections.

Find out which wire is for high beam and which one is for low beam using a multimeter, if you don't have one already then any cheap multimeter will do for this purpose. In other words find the wire that outputs roughly 12V when the dipped beam is on and 0 when it is off then do the same for the high beam.

Make sure that you insulate the solder joints well with heat shrink or at the very least electrical tape, you don't want the wires touching the frame and blowing your fuse while driving in the dark.
