Simplified Adapter for Converting from Vacuum Turbo to EL Turbo This adapter is designed for use when switching from a vacuum-controlled turbo to an electric actuator (EL) turbo. One plug connects to the N75 connector from the engine wiring harness. The other side connects to the electric actuator. The O-ring should be grounded securely to a solid chassis ground. High-temperature-resistant silicone wires are used. Note: The ECU software must be modified to support the EL turbo. Why Choose the EL Turbo? The EL turbo is generally preferred due to its faster response time and the elimination of vacuum-related issues. Examples: Example 1: 2260 EL on D1 Example 2: D2 (EU3, vacuum) converted to EL turbo (EU4)
