These phone jacks are big and clunky, which not only makes them easy to work with, but also easy to keep clean. They can handle a lot more brute force than some fancy tiny connector that you are probably tempted to use.
Take one of these and solder it to the contacts that feed the LED on the circuit board. Thus we are tapping the power that runs the LED.
LEAVE THE LED ATTACHED ! you still want some sort of indicator that tells you if you have a charge or not.
