but where do i connect the wires to of the 2.7 volt circuit
I drawed what you say,
That will be 3 and 5?
i can't find it in the datasheet so i don't think it has it.
Not sure I follow the logic there. I can't find next weeks winning lottery numbers but I am sure there are some.Measure the resistance of the coil with a meter, if it is different in one direction to the other then there is a diode in there.If you haven't got a meter then get one, they are very cheap and you have no business doing electronics without one.
Where is 4 for?
