Wow. This is an old thread.
After doing about 1000 of these UMC / HPWC to J1772 conversions since this thread started, let me first tell you that our method for powering the LED was not adequate. We were pulling 3.3 volts off the "blue" wire (which would normally power the RF transmitter to open the charge port door on the car).
That piece of information will save you some grief. How you might handle the power is up to you. I recommend a simple battery that turns on when you press the disconnect switch.
Use any 3.3v powered LED. There are lots of choices.
