HOW TO USE:

• Preparation: Ensure the engine is cool and the battery is disconnected. Gather necessary tools, including wrenches, sockets, and potentially fuel line disconnect tools.
• Remove Existing Carburetor/Throttle Body: Carefully remove the existing carburetor or throttle body from the intake manifold. Take note of all vacuum lines, fuel lines, and electrical connections for proper reassembly or replacement.
• Install the FiTech Throttle Body: Place the provided gasket onto the intake manifold. Position the FiTech 30039 throttle body onto the gasket and secure it using the included hardware. Tighten the bolts to the manufacturer’s recommended torque specifications.
• Connect Sensors: Connect the wiring harnesses to the included TPS, IAC motor, and T-MAP sensor on the throttle body. Ensure connections are secure.
• Install Fuel Injectors (Not Included): Install the appropriate fuel injectors into the designated ports on the throttle body. Ensure they are properly seated and secured.
• Connect Fuel Lines: Connect the fuel lines to the fuel rails on the throttle body. This may require adapting existing fuel lines or installing new ones suitable for EFI systems. Ensure all connections are tight and leak-free.
• Connect Throttle Cable: Attach the throttle cable to the throttle body linkage. Adjust the cable to ensure proper throttle operation and return.
• Connect Vacuum Lines: Connect any necessary vacuum lines to the appropriate ports on the throttle body.
• Connect Wiring: Connect the main wiring harness from the EFI system (not included) to the throttle body and sensors according to the EFI system’s instructions.
• Final Checks: Double-check all connections, ensuring everything is secure and properly installed.
• Initial Setup and Tuning: Follow the instructions provided with your EFI system to set up the ECU and perform initial tuning. This may involve inputting engine parameters and calibrating sensors.
