If you own a 1999 Honda Civic and need to repair or replace your distributor, you’ll need a good understanding of the distributor wiring diagram. The distributor is a critical component of the ignition system, and the wiring diagram ensures that all electrical connections are properly made, and the engine runs smoothly. In this article, we will discuss the wiring diagram layout, common issues that occur with the Honda Civic distributor, and some frequently asked questions.
Wiring Diagram Layout
The Honda Civic distributor wiring diagram is relatively simple to understand. There are two types of distributors in the 1999 Civic: the internal coil and external coil. The internal coil distributor has the coil inside the distributor cap, while the external coil distributor has the coil mounted externally, with a spark plug wire leading from the coil to the distributor cap.
The wiring diagram for both distributors is similar, with some differences in the placement of wires. Here is a general overview of the wiring diagram layout:
| Pin | Description | Color |
|---|---|---|
| 1 | Ignition Control Module Signal | Green/Yellow |
| 2 | Ignition Coil Control Signal | Blue |
| 3 | Ground | Black |
| 4 | Ignition Coil Ground | Green |
| 5 | Distributor Signal | Yellow/Green |
The wiring diagram shows how each pin on the distributor plug is connected to the ignition control module, ignition coil, ground, and other components. It also shows the color of each wire, making it easy to identify the correct wire when troubleshooting.
