Ignition Switch Mopar Electronic Ignition Wiring Diagram

If you’re looking to upgrade or repair the ignition system in your Mopar vehicle, you’ll want to take a close look at the wiring diagram for the electronic ignition system. This article will provide an overview of the Mopar electronic ignition system and offer helpful tips for wiring and installation. We’ll also answer some common questions about this system and provide a useful table of specifications and part numbers.

What is the Mopar Electronic Ignition System?

The Mopar electronic ignition system was introduced in 1972 as an upgrade to the previous points-based ignition system. This system offered improved reliability and performance, making it a popular choice for Mopar enthusiasts. The system uses an electronic control module (ECM) to regulate the ignition timing, replacing the mechanical distributor used in the points-based system. The system also includes a high-energy ignition coil and a ballast resistor to enhance spark output.

The Mopar electronic ignition system was offered as an optional upgrade on a variety of Mopar vehicles, including the Dodge Challenger, Plymouth Barracuda, and Chrysler 300. The system is still available today as a replacement for older vehicles or as an upgrade for newer Mopar models.

Wiring Diagram Overview

The wiring diagram for the Mopar electronic ignition system is relatively simple, but it’s important to follow the correct wiring procedures to ensure proper operation. The diagram includes connections for the ignition switch, ballast resistor, ignition coil, distributor, and various other components.

One of the key features of the wiring diagram is the use of a ballast resistor. This resistor is designed to limit the current flowing to the ignition coil, preventing it from overheating and damaging other components in the system. The ballast resistor is typically located near the ignition coil and should be replaced if it shows signs of wear or damage.

Another important element of the wiring diagram is the ignition switch. This switch is responsible for providing power to the ECM, distributor, and other components when the key is turned in the ignition. Proper wiring of the ignition switch is crucial for the system to function correctly.

Tips for Wiring and Installation

Wiring and installation of the Mopar electronic ignition system can be done by a skilled mechanic or a knowledgeable enthusiast. Here are some helpful tips to keep in mind:

  • Before beginning the installation, make sure you have the correct wiring diagram for your vehicle and ignition system.
  • Ensure that all components are properly grounded to the vehicle chassis.
  • When installing the ballast resistor, make sure it is properly mounted and not in contact with any other components.
  • Double-check all wiring connections for proper placement and security.
  • Follow the manufacturer’s instructions for setting the ignition timing.
  • Once installed, test the system for proper function before taking your vehicle on the road.
