Where is the waste gate exhaust bypass valve on a 2004 Dodge Ram?

On a 2004 Dodge Ram, the wastegate is integrated into the turbocharger itself. It's not a separate, externally accessible component like a bypass valve on some other turbocharged systems. You won't find a separate wastegate actuator or valve to adjust. The wastegate is controlled internally by the turbocharger's internal components and the engine's computer.
