CEL, Service parking brake + ESC and rough running engine troubles

[Rya]

I have a 2020 Sierra 1500 LTD with 85000 miles and all of a sudden the brake light flashed than the check engine light stayed on and unable to use cruise control. The truck strayed to run and break rough. I hate to see what this is going to cost me when I get back from this trip. From what I have been reading this is the wiring harness issue between to the ESC
