It shows up in catalog listings spanning 1979 to 1983, which lines up with the amplifier-box era of Triumph wiring. If your amplifier box is grounding out intermittently, or you're chasing electrical gremlins that come and go with vibration, a tired or corroded earth lead is worth checking before you start replacing bigger components.
We don't have more detail on this one beyond what's in the parts book. If you're not sure this is the exact lead your bike needs, call the shop and we'll confirm fitment before you order.
