'06 4L65-e TCC signal?

[HwyStarJoe]

I searched back a couple years and couldn't find an answer.

I'm trying to find the correct signal\wire to tap into for my brake light switch to use for the torque converter control on my 4L65-e.
There are 2 TCC signal wires between the trans and the TCM, and I don't know which (or both) I need to wire up to the brake switch.
The trans and controller are from an '06 GTO.

Thanks for any help!

Tap into the tcc solenoid not the tcc pwm solenoid. Greg

Excellent!
That helps a lot! Thank you Greg.

Hey all,
One more electrical question about the trans... Do I need to supply the TCM with (switched or constant) 12V on Pin 31, in the same manner the ECM is?
Thanks

Let me add the wiring diagram for a better picture of what I'm talking about...

It seems to make sense to wire the TCM the same way the ECM is powered as per the factory wiring diagram. Just looking for confirmation before I hide all the wiring.
Thanks
