Does anyone know what this wire and button is?

Hey all. I’m noticing most of the underneath of my wires are hanging on this Camaro that I bought recently. Does anyone know what this blue button is? Is it a kill switch? I’ve never had to use it when starting up. Is it onstar? I pushed it a couple times while the car was on it did not do anything.
