Holley EFI Gen III Hemi VVT and SRV harnesses offer control. 2009+ Gen III Hemi engines rolled off the showroom floor with Variable Valve Timing (VVT). Now, both Holley 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. But the fun does not stop there! If you are using a stock intake manifold that came from the factory with the Short Runner Valve (SRV), Holley also has a 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, and any 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 simply plug into the factory SRV actuator in the intake manifold
