It's actually far less complicated. The aftermarket trailer brake is an external, binary system operated by the brake switch. Brake lights activated, trailer brakes activate too. There is no interaction with the StabiliTrak from a networking perspective. Physical force acting upon the tow vehicle could theoretically cause the Stabilitrak system to intervene, but it's not sophisticated enough (on the OP's vehicle) to consider outside forces acting upon it. It's going to take input from the sensors contained within the vehicle to attempt to correct what it perceives as an out-of-control situation independent of outside variables (like towing a trailer, tornado, ice, flooded road, bald tire, civil unrest, lava, black hole, etc.). It will make a best effort to maintain the assumed, intended direction irrespective of any of these things.
I don't think the OP was looking to tie a brake controller into his StabiliTrak system. Rather, he was referencing some verbiage in the manual that says a brake controller does not integrate into the Stabilitrak system. That statement is true on that model year truck.
GM does offer an integrated brake controller on its late model trucks that, when in Trailer Mode, considers potential sway and grade braking where StabiliTrak may intervene. In that case the system does indeed consider the fact that there are outside forces acting upon it. The OP's vehicle doesn't have that.
