Tapping into a 6.1L TPS to control 4l603 Trans

I am going to be using a 4l60e trans with my 6.1 swap (i want lockup and a few other features of the 4l60e), but I also have drive by wire throttle. I know that trans controller needs to see the Throttle position to control line pressure and shift points, but wondered if anyone know exactly how to connect into the TPS. Thanks in advance for the help.

I think switching over to a cable operated TB migh be the way to go if your using a 4l60e. It's plug and play with controllers from Compushift, PCS, TCI etc...
