Torque convertor lock up indicator ?????

Is there a way to install and LED light that will let me know when the TC is locked? If so, how?

the best way to just hook up a LED is to run the hot lead to a switched power source and tap into the wire that runs from the pcm to the TC. when the pcm calls for a TC lockup it effectivly grounds it to cause the lockup. when the ground is made to lock the TC it also completes the ground for the LED causing it to light up.

I just added a little helpful note above in red.
