IN 1969 the easiest source was the yellow wire at the voltage regulater. It is a direct run form the ignition switch. The 73 Hornet I parted was still equipped with a motorolla charging system and it was the same. I'd expect to find the same yellow wire at the regulater of your Javelin. Your mileage may vary!
