I would like to test my micro molex connector crimping and insertion into shells skills using the flap position switch as the test bed. I have connected the switch to the harness with three wires: Orange, blue and green from switch to orange blue and white in the Steinair harness. Green and white are probably ground and the orange and blue are probably for the position of the flaps, up and down. Is there an easy way to test whether my connections at the switch are competent using the three wires currently terminating in the large dSub at the forward end of the Steinair harness?
