British Wiring Harnesses for Classic British Motorcycles
British Wiring produces high-quality reproduction harnesses that are designed to be exact copies of the original Lucas harnesses. These reproductions are popular among classic motorcycle enthusiasts for restoration projects, as they offer the authenticity of the original design while providing new, reliable wiring.
Bring your motorcycle wiring project together with replacement harnesses from The Bonneville Shop’s British Wiring collection. Our range includes main wiring harnesses for classic Triumph models, selected shared Triumph and BSA applications, and separately listed headlamp and tail-light wiring. Cloth-bound and PVC-bound options are available for several applications, giving you a choice of outer finish when selecting replacement wiring.
Main Wiring Harnesses for Triumph
Our selection covers Triumph T90, T100, TR6, T120, TR7, T140, and TR25W applications, with listings ranging from selected 1963–1964 twins to 1979–1980 TR7 and T140 models. Separate harnesses are listed for different model-year combinations, including road models and selected T100C, TR6C, and T120TT applications.
Start with your motorcycle’s exact model and year, then compare the listing’s application details and part-number references. If your motorcycle has been modified, check the electrical components actually fitted before choosing a harness.
Cloth-Bound and PVC-Bound Options
The collection includes cloth-bound and PVC-bound harnesses, with both finishes listed for several Triumph applications. Examples include selected 1965 and 1966 twins, 1968 T100C/TR6C models, and 1968–1970 TR25W singles.
Choose the outer finish you prefer, but confirm the application independently. A matching finish does not establish that a harness is correct for your motorcycle.
Separate Headlamp Wiring
For selected 1971–1972 Triumph TR6C, TR6R, T120R, and BSA A65 applications, our collection includes separately listed main and headlamp harnesses. The main harness carries references 54959629 and 99-1222; the headlamp harness is listed under 54959535.
Check which wiring section your repair requires before ordering. Review the contents of each listing rather than assuming a main harness includes the separate headlamp section.
Lucas-Type Tail-Light Harnesses
Our selection also includes 30-inch and 36-inch Lucas-type tail-light wiring harnesses. Both list Triumph, Norton, and BSA applications, while the 30-inch version also lists Matchless and AJS. (The Bonneville Shop)
Measure the required wiring route and check the product details before selecting a length. These are rear-light wiring items, not substitutes for a main harness.
