LLY Tap shift

Hello, I have an LLY duramax and 5 speed allison in my GU patrol. I am looking into the tap shift application for this model, I can find details regarding the resistances/voltages required to signal the TCM for normal mode/up/down shift request but am unable to find to which pin on the TCM this needs to be connected to.

Does anyone know what pin the signal needs to be connected to?

Fleece makes a kit, they might have instructions on their web site, or maybe purchase a kit from them.
