Maybe it was a breeze for everyone, but for me to understand the flap switch was a time consuming excercise. I finally got it and tested it with my 12V power supply. There are 6 connectors on the switch labeled from 1 through 6. Connector 6 is the power (V+) connector and connector 3 is the ground connector. I used fast on connectors for 6 and 3 with an additional wire connecting 6 to 1 and 3 to 4. The Flap motor is connected to 2 (V-) and 5 (V+). Connectors 1, 2 4 and 5 use screw logs. This gave me a momentary up and down voltages to the flap motor.Wired up everything and will retest the switch. Wired up the second switch to the clock to make it possible to control fight time. To do this terminal 4 is grounded through this switch. Also wired up the strobe trigger switch and the TruTrak on/off switch.
