In some cases, actuator connectors in your 6.7L Cummins can become loose or break causing a poor connection between the connector and the actuator. This can lead to intermittent issues or a complete failure of the actuator all together. The Fleece Performance HE300VG Turbocharger Actuator Pigtail will allow you to repair the connector and ensure a proper connection between the connector and turbo actuator. This kit includes heat sealable butt-style connectors.
