Technical No flashing lights

Orange-blue stripe Right rear turn signal/brake
Green- Orange should be the left rear turn signal/brake
White - blue right front turn signal
Green-white Left front turn signal
Blue = Flasher
Green = stop light switch

With the switch in the middle you should be able to hook a continuity tester or ohm meter to the green wire and have continuity to the orange-with blue stripe and the Green with orange stripe wires. That is your brake lights.

With the tester hooked to the blue wire you should have continuity to Green-orange stripe and green-white stripe when set for left turn signal and Orange -Blue and White- blue when you have the right turn signal on.

There is no 4 way on that switch so you don't worry about 4 way flashers for now.
