As per the title, acquired some more parts. Most are Yamaha new old stock, but I'm having problems pinning down these two.

I'm pretty sure I know what they are, just not the make that they're for.

The part in the first set of pictures looks to me like a side stand switch and the three wires are coloured brown/red, green/blue, brown - does anyone know which manufacturer used this combination? Also, the number 403 is stamped on it.

The part in the second set of pictures looks to me like a fuel level sender (that is a float on the inside) and there is a single wire. ND and S8 are stamped on it. Does anyone have a general idea of which manufacturer might have used this?

Many thanks.
