Check Compatibility:
- Ensure the ignition computer you have is compatible with the Chevy 350 and the throttle body injection system you're using.
Wiring Diagram:
- Refer to the wiring diagram for the ignition computer and throttle body injection system. This will provide specific instructions on how to connect the ignition computer to the engine and other components.
Computer Inputs and Outputs:
- Identify the input and output connections on the ignition computer. This typically includes connections for the ignition coil, fuel injectors, sensors (e.g., coolant temperature sensor, oxygen sensor), and the vehicle's battery.
Sensor Connections:
- Connect the appropriate sensors to the ignition computer. These sensors send signals to the computer that help it adjust ignition timing and fuel injection.
Ignition Coil and Injectors:
- Connect the ignition coil and fuel injectors based on the wiring diagram. Ensure the polarity is correct if the components have specific positive and negative terminals.
Power and Ground:
- Connect the power and ground terminals of the ignition computer. These typically come from the vehicle's battery and a suitable grounding location on the chassis.
Vehicle-Specific Adjustments:
- Depending on the specific engine and vehicle combination, you may need to make adjustments to the ignition timing and fuel injection parameters within the ignition computer's settings. Some computers have adjustable settings, while others may require programming or tuning by a professional to optimize performance.
Test and Verify:
- Once the ignition computer is connected and wired according to the instructions, start the engine and verify that it's running smoothly. Check for any error codes or malfunctions by using diagnostic tools.
Remember, installing and setting up an ignition computer can be complex, especially if you're not familiar with automotive electrical systems. If you're unsure or encounter difficulties, it's always a good idea to seek professional help or consult with an experienced mechanic or automotive electrician.
