Old Britts – Notes About the 06-8069 1971–1974 Main Wiring Harness
Download the complete PDF version using the green download button at the top right of this page for an Old Britts technical note covering the 06-8069 main wiring harness used on 1971 through 1974 Norton Commando models. This reference is intended to help with harness installation and includes both the full wiring diagram and a clear photograph identifying the front harness pigtails that connect to the ignition-related components.
The article explains that older motorcycle wiring may have been altered over the years, so the existing harness on a bike may not match the expected color codes exactly. To reduce confusion during replacement, the guide labels the relevant pigtails for the coils, ballast resistor, points harness, condenser and red ground wire, making the front ignition-side connections easier to identify.
The included wiring diagram provides the larger electrical layout for this harness, while the labeled harness photograph gives a more practical view of the actual loose connectors encountered during installation. Together, they make this a useful quick reference when fitting or checking the 06-8069 Commando main wiring harness.
