Left hand switch cluster

I have a brand new left switch cluster that came with the 74 commando basket case I am rebuilding. It has a red toggle switch on it and a angled plastic appendage with a brown and blue and white wire on it. Neither of these wires are in the wiring diagram and I have no idea what this additional piece is and how it fits or even if this is the right switch cluster. Any ideas would be very helpful
Thx

That's a Triumph RH switch cluster. The plastic appendage is the front brake light switch (disc brake).

OK thanks I thought I might have something odd here Maybe I can sell this one
