HARNESS 71-2 T120/A65 MAIN
Lucas cloth-wrapped main wiring harness for 1971-72 oil-in-frame 650 twins, used with a separate headlamp harness.
This is the main wiring harness for the 1971-72 oil-in-frame 650 twins, covering both the Triumph T120/TR6 line and the BSA A65. It's a Lucas cloth-wrapped harness, and the catalog lists it under this main-harness figure alongside the headlamp and flasher lamp wiring, so it's the core loom that runs the bulk of the bike's electrics rather than the separate headlamp shell harness.

For these two years Triumph and BSA split the wiring into two harnesses, and this part number is the main one - it works alongside the headlamp harness sold separately, not in place of it. If you're rewiring a '71 or '72 650 twin you'll want both pieces on the bench at the same time so you're not missing connections partway through the job.
The older reference number WW19086C shows up as an alias for this same harness, so if that's what's printed in your parts book, this is the part it points to. Appearance in our records is limited to the one catalog listing, so if you have any doubt about which harness variant your bike left the factory with, give the shop a call before you order.
