X1 pin 9 0.5 L-BU/WH 6311 Brake Switch Signal (goes to underhood fuse block P3, wire also goes to TCM, both hook to tcc brake switch at brake pedal, 12v+ hot with brakes applied. Open when NOT on the brakes.)
and 6311 0.5 L-BU/WH to TCM plug.

I do not have any brake lights connected. I will have to wire in a light bulb and see if that works.

I currently have the stock brake switch installed and wired like:
Orange 12v one side of switch

Other side of switch=
White- Brake light feed
Brown- to remote start brake pedal signal
Blue- to PCM/TCM brake light trigger pin 9
