HARNESS,CLOTH ET TWINS 65-67 C MODEL TRIUMPH
Cloth-bound main wiring harness for 1966-67 Triumph C-model twins with E.T. magneto ignition and no ignition switch.
This is the main cloth-bound wiring harness for the 1966-67 Triumph twins fitted with E.T. (energy transfer) magneto ignition and no ignition switch, listed in the parts books under the A.C. magneto ignition coils and direct lighting figures. Part number 54937097, also carried under the trade number MC.131PB, ties together the charging, lighting, and ignition circuits that run off the magneto system rather than a battery-based ignition switch setup.

On these C-model machines the harness routes power from the magneto and lighting coils out to the headlamp, tail lamp, and other direct-lighting circuits, since there's no separate ignition switch in the loop to control things. It's a cloth-covered loom, consistent with the catalog listing and the era it comes from.
The catalog ties this specifically to the 1965-67 span and the C-model machines noted in the description. If you're not sure whether your bike uses the E.T. magneto setup without an ignition switch, check your existing harness routing and switchgear before ordering, or give us a call and we'll sort out fitment.
