however, if you make this connection, the LED turns on as you turn off the car, instead if you take the positive power from Pin 1 explained in post 1 of this THREAD, it works only when you close the car.

I tested it out and this works perfectly, you can adjust the length of blink and the pause seperately so it easy to sync according to an original alarm.
have you always connected to pin 1, of the first post?

I wanted to ask you, if I use this pre-printed circuit, which has a power supply starting from 5v, if I connect it to pin 1 which has, when the machine is switched off, 4.6v, which you think is off in this circuit or is powered and makes the led work even with a car?
