If you’re planning to install Fitech EFI system for your engine, you’ll need to have a good understanding of its wiring diagram. Fitech is a popular brand that offers a wide range of EFI systems that are designed to work with various types of engines. In this article, we’ll discuss the basics of Fitech wiring diagram and provide you with a step-by-step guide on how to wire your Fitech EFI system.
What is Fitech Wiring Diagram and Why is it Important?
Fitech wiring diagram is a schematic representation of the electrical connections in your Fitech EFI system. It shows how the different components of the system are wired together, and how they interact with each other to control the fuel injection process. Understanding Fitech wiring diagram is important because it allows you to install and troubleshoot the system more effectively.
Before you start wiring your Fitech EFI system, you should have a basic understanding of how it works. Fitech EFI system is a self-learning system that uses sensors to monitor the engine’s performance and adjust the fuel injection accordingly. The system consists of several components, including the ECU, fuel pump, fuel injectors, sensors, and wiring harness.
How to Wire Your Fitech EFI System
Step 1: Mount the ECU and Wiring Harness
The first step in wiring your Fitech EFI system is to mount the ECU and wiring harness in a suitable location. The ECU should be mounted in a position that is away from heat and moisture. The wiring harness should be routed and secured to prevent damage or interference with other components.
Step 2: Connect the Fuel Pump
The next step is to connect the fuel pump to the wiring harness. The fuel pump should be connected to the Pink wire on the wiring harness. This wire provides power to the fuel pump relay, which in turn activates the fuel pump.
Step 3: Connect the Fuel Injectors
The fuel injectors should be connected to the wiring harness using the Red and Blue wires. The Red wire connects to the positive side of the injector, while the Blue wire connects to the negative side.
Step 4: Connect the Sensors
The sensors should be connected to the wiring harness using the appropriate wires. The most important sensors in the Fitech EFI system are the air/fuel ratio sensor, coolant temperature sensor, and throttle position sensor. These sensors provide critical data to the ECU, which uses it to adjust the fuel injection.
Step 5: Connect the Battery
The final step is to connect the battery to the wiring harness. The Black wire should be connected to the negative terminal of the battery, while the Red wire should be connected to the positive terminal. Make sure that the battery is fully charged before connecting it to the system.
