Tis my understanding the wire with the red heat-shrink is the trigger lead for the high beam, the plain black wire is trigger for the low beam, and the white wire is a common ground (to the relays).
If it basically works, but high and low are switched, flip-flop the two small black wires (one has the red heat shrink) from the Murphs harness in the OEM socket.
If you have time, ground the white lead of the Murphs harness to someplace on the frame. Then insert one of the black leads into one of the three tabs in OEM socket until one light (hi or low) works as expected. Insert the other black lead into one of the remaining two until it also works as expected. Now remove the white wire from ground and plug it into the remaining tab in the OEM socket. Go ride.
