Pretty screwed

On the road & check engine light came on a couple days ago. Idk how I didn’t notice the belt had snapped & tore a connection. Message kept popping up to idle truck to cool down even though temp was at normal 210. I’m gonna attempt to replace the belt, but I’m trying to figure out how I’m gonna fix the connection. It’s a long shot, but do y’all know what connection it could possible be?? 2021 2500 6.6 L5P

Thanks!
