Question about l.e.d. Placement on variable volt

[basementcat]

Using this wiring diagram where would I wire an
Led to light when the fire button is pressed?

I'm guessing the same lines as the atty connector?

You would put it on the wires going to the atomizer connector. One leg of the LED goes to the positive wire the other to the negitive. Dont forget to add a resistor or it will burn up. Doesnt really matter if the positive or negitive leg gets the resistor just as long as it gets one.
