Wiring harness (99-0000)
Main Lucas wiring harness (54957095, formerly 99-0000) for the headlamp, switches, and tail lamp circuit.
This is the main wiring harness listed under Lucas number 54957095, also carried in the older parts-book numbering as 99-0000. It shows up in the catalog under the HEADLAMP, WIRING HARNESS, SWITCHES AND TAIL LAMP figure, and the second appearance ties it specifically to the TR6R and T120R.

The harness is the trunk line running from the headlamp shell back through the switches to the tail lamp, carrying the circuits for lighting, switching, and the rest of the electrical system on the bikes it was cataloged for. Getting the correct harness matters because the routing and connector layout are matched to the specific switch and lamp assemblies it was built for - the wrong harness means splicing and improvised connections instead of a clean factory fit.
Our record on this one is limited to the two catalog entries above, so if you're matching it to a specific machine, have your parts book or the switch/lamp hardware on hand and we'll confirm before you order.
