Duraspark Ignition Module Wiring Diagram

The Duraspark ignition module was a popular replacement for the factory ignition module in older Ford vehicles. This module offered greater reliability and performance than the factory option, making it a favorite among enthusiasts. However, installing the Duraspark ignition module requires a bit of wiring know-how. In this article, we’ll go over the Duraspark ignition module wiring diagram and provide some tips and tricks for installing this module in your vehicle.

What is the Duraspark ignition module?

The Duraspark ignition module is an electronic control module that regulates the spark output of an ignition system. This module was developed by Ford Motor Company and was first introduced in the late 1970s. The Duraspark module replaced the outdated points-and-condenser ignition system and was a significant improvement in terms of reliability and performance.

The Duraspark ignition module consists of two parts: the primary module and the ignition control module (ICM). The primary module controls the coil and distributor, while the ICM controls the timing advance and retard functions. Together, these modules ensure that the ignition system produces a strong, consistent spark at the right time.

Wiring the Duraspark ignition module

Wiring the Duraspark ignition module requires a few modifications to your vehicle’s wiring harness. The following wiring diagram shows how to wire the Duraspark module:

Wire Color Function
Red Battery positive
White Distributor ground
Green Ignition control signal
Black Ground
Orange Distributor positive
Purple Tachometer signal

Before you begin wiring the Duraspark module, it’s important to disconnect the battery to prevent any electrical damage or injury. Once you’ve disconnected the battery, locate the factory ignition module and remove it from the vehicle.

Next, splice the red wire from the Duraspark module to the battery positive wire. The white wire should be grounded to the distributor housing, while the green wire should be connected to the ignition control signal wire (usually a green wire with a red stripe).

The black wire from the Duraspark module should be grounded to the vehicle’s chassis. The orange wire should be connected to the distributor positive wire (usually a red wire). Finally, the purple wire from the Duraspark module can be connected to the tachometer signal wire (if your vehicle has one).

Tips for installing the Duraspark ignition module

Here are some tips to keep in mind when installing the Duraspark ignition module:

  • Make sure you use high-quality connectors and wiring to ensure a reliable connection.
  • Take your time when splicing wires and ensure that all connections are secure and properly insulated.
  • Use a multimeter to test your connections and ensure that the module is receiving power and sending signals correctly.
  • Double-check your wiring before turning the ignition on to prevent any electrical damage or injury.
