Need help identifying this part

[Plumber101010]

2020 gmc savana G2500. Between the two front seats underneath the mat there are two big control modules. I drilled holes through them. As well as the wiring harness that feeds them. Dealer wants $1250 to replace all. I don’t think it’s a bad price because I know the one airbag control module itself is $400. But there’s a second large black box right below it that he said was for a rollover but I can’t find it anywhere online to get a price! Trying to decide if I should do it myself and save money but he said he’s giving me an extra good deal. Any search I do just keeps coming up with the main airbag module and I don’t see anything for this second box. See picture. And thanks!!!

That looks like the yaw sensor, it's for ABS and Stabili-Trac.  Be advised if you replace it I think it has to be programmed to the vehicle:

Thank you! That makes sense because my stability track light is on as well!!!

If I have a blue driver diagnostic tool do you think that will program it??

Not sure, sorry.  Might need GM Techlink.
