What bike does this MC fit?`

[Big T]

I've got a bin full of 1100E/1150 parts that I acquired long ago

I found this rear MC and I haven't been able to match it to bike

The electrical connection is what's puzzling me, it doesn't show in any parts fiche

Must be a low level brake fluid warning light switch.

I's thinking the same thing, but I don't remember anything that had a brake fluid level light.

Agreed, it goes with the other 1100 parts I have.
I was going thru the FSM for the 1100 and one illustration showed the wires. The other ones didnt

These dang birthdays, another few yrs. & I won't remember my name. I remembered the batt. water level light, would tell you if water was low in the cell the sensor was in. I had to go look at the manual, saw it there brake fluid light, & still don't remember it. Glad it got figured out.
