There are two posts on the brake/stoplight switch. One is "hot". The other is not. Red wire from turn signal switch goes to the brake switch post that is not hot.

You should be left with a black and a blue wire. If your flasher is 2 pole, twist the black wire and blue wire together, and fasten both to the post marked "L".
If your flasher is three-pole, fasten the black wire to "L", the blue wire to to "P". Whether you have a 2 pole or 3 pole flasher, fasten your hot wire from the ignition to the flasher pole marked "X"
