If you are purchasing this electronic ignition, you must also upgrade your spark plug wires.
Standard Lucas wires (or the ‘old’ ones you have on your Healey) will not work with the new electronic ignitions.
If you do not upgrade, you will run the risk of burning out this electronic ignition and Petronix will not warranty it.
