If you own a Ford vehicle, the chances are that you have come across several confusing wiring diagrams. One of the most prevalent ones is the Ford HEI distributor wiring diagram. This guide will help you understand all you need to know about the Ford HEI distributor wiring diagrams.
What is a Ford HEI Distributor?
A High Energy Ignition (HEI) distributor is an electronic system that uses a solid-state module to trigger the spark plugs. The HEI system replaced the outdated points and condenser ignition system. Ford HEI distributors have become popular because they offer easy installation and improved performance. They have a built-in ignition module and a magnetic trigger that replaces the points and condenser. They are easy to install and come with a wiring diagram that guides you through the installation process.
Understanding the Ford HEI Distributor Wiring Diagram
Before you begin installing your HEI distributor, you need to have a better understanding of the wiring diagram. The diagram shows the connection between the distributor, the ignition module, and the battery. The HEI distributor has four wires that connect it to the rest of the ignition system.
Wiring the HEI Distributor
The first step in wiring the HEI distributor is identifying the wires. The distributor has a red wire that connects to the positive side of the battery, a black wire that connects to the negative side of the battery, and two smaller wires that connect to the ignition module. The smaller red wire connects to the “Batt” terminal on the ignition module, and the smaller white wire connects to the “Tach” terminal on the ignition module.
The wiring process is simple and involves connecting the wires as follows:
| Wire Color | Connection |
|---|---|
| Red | Positive side of the battery |
| Black | Negative side of the battery |
| Small Red | “Batt” terminal on the ignition module |
| Small White | “Tach” terminal on the ignition module |
Wiring the Ignition Module
The ignition module is the brain of the HEI distributor. It is responsible for controlling the spark plugs and ensuring that the engine runs smoothly. The module has four terminals labeled B, C, G, and W. The wiring process involves connecting the wires to their respective terminals.
The wiring process is simple and involves connecting the wires as follows:
| Wire Color | Connection |
|---|---|
| Small Red | B terminal on the ignition module |
| Small White | W terminal on the ignition module |
| Distributor | C terminal on the ignition module |
| Ground | G terminal on the ignition module |
