How can you do a double star when you only have three coils, ? if you take the left hand (incomplete)diagram on pic 3, and link U1 to V2, V1 to W2 and W1 to U2, and connect the phases to U1, V1 and W1 the motor is in Delta, but this is not the problem the OP is having, as I said above, connecting the motor is easy, even though the wiring diagram supplied is incomplete, it is wiring the switch to the motor to make the change between star and delta with all the coils kept in the correct sequence that is the OP's problem!
