Default Need help identifying what these wires are for

Hi,
I'm looking for a used Tahoe on iaai/copart auctions - not a piece of junk but rather hail-damage or a car recovered from theft.
Usually I'm able to get a lot of info from the pics that are posted, but sometimes (especially if it is related to drivetrain or electrical wiring) I need some help in understanding the car's condition.

Could someone, please, help me with the information what are the red wires on the picture below? Are there any electronic modules missing? Is the car driveable? Any help will be greatly appreciated!


Best Regards,
Kristoff

On photos of Tahoe LS, sometimes I can see some kind of yellow module sticking out in exactly the same place as these wires. (photo below). Could it be Chevrolet Connected Access module?

not sure what it is but most factory installed items would not stick out from the dash like that

And factory doesn't use crimped on blue insulated connectors with 2 wires of the same color.

I think I found out what the "yellow thingie" is:
Chip

Doesn't seem to be related to red wires in the first pic, though.
Noone knows what they are?
