Holley EFI GEN III HEMI VVT and SRV Harness 558-132
Type: Harness
2009+ Gen III Hemi engines rolled off the showroom floor with Variable Valve Timing (VVT). Now, both Terminator X and Terminator X Max ECUs will allow you to control and tune the VVT with the use of the plug and play VVT harness. The fun does not stop there though! If you are using a stock intake manifold that came from the factory with the Short Runner Valve, we also have a new plug and play sub harness that will allow you to utilize the SRV actuator and capitalize on its low RPM torque benefits.
Features:
- Plug and play with the factory Gen III HEMI VVT sub-harness
- Use Holley EFI HEMI Main Harness connecting to the Power Tap and Input/Output connectors
- Provides control of VVT solenoid under the intake manifold
- SRV (Short runner valve) connector pre-wired into the sub harness allowing you to plug into the factory SRV actuator in the intake manifold
