I have a on-off switch that'll use for a kill switch for my car using the gas pump. The switch says 6A/125V 3A/250V 22 AWG. For my purpose it needs to handle 12V 20 Amps max.

You cannot use a 6A switch with a 20A load. You may also run into issues with lower voltage rating at DC, but that hardly matters as you are already so far beyond the current rating.
