Ignition Coil Wiring Harness Chart or Diagram
An ignition coil wiring harness is a component of an internal combustion engine’s ignition system. It consists of a set of wires that connect the ignition coil to the spark plugs. The ignition coil provides the high voltage necessary to create a spark across the spark plug gap, which ignites the air-fuel mixture in the engine’s cylinders.
There are a few different types of ignition coil wiring harnesses, depending on the make and model of the engine. However, they all serve the same basic purpose. The most common type of ignition coil wiring harness is a “daisy chain” harness. This type of harness has a single wire that runs from the ignition coil to each spark plug. Another type of ignition coil wiring harness is a “star” harness. This type of harness has a separate wire running from the ignition coil to each spark plug.
When creating an ignition coil wiring harness, it is important to use the correct type of wire and connectors. The wire should be rated for the high voltage that will be passing through it. The connectors should be able to withstand the heat and vibration of the engine. It is also important to make sure that the harness is properly routed and secured. A poorly routed or secured harness can cause problems with the ignition system.
Here are some of the benefits of using a properly designed and installed ignition coil wiring harness:
- Improved engine performance
- Reduced emissions
- Increased fuel economy
- Longer spark plug life
If you are experiencing problems with your engine’s ignition system, it is important to have the ignition coil wiring harness checked. A faulty harness can cause a variety of problems, including misfires, poor performance, and increased emissions.
