Forward toward the dashboard for high beams, back toward the wheel for low, then pull against the spring to flash high beams.

The quality is just so poor. 12 uses out of first one, 8 uses out of 2nd one and the last one lasted 3 uses and gave out in the dark at the start of a 1,283 mile trip over 6 days. I had to sit on the side of the road and wait for the sun to come up. A buddy had a two position 50 year old Sunbeam light switch we installed hanging under the dash on the first day of the trip, whew.

With your cut-off switch on tap first one then the other of the wires mentioned above onto the brown and you should soon see which has the short - if it's still present.
