I need to install a ceiling light with pull chain. I purchase the
ceiling light and pull chain
separately, they don't come together.
There are black and white wire come from ceiling and the ceiling light
has black and white wire also.
I know I should connect the black and black, white and white wire
together.
But how to connect the pull chain wire? The pull chain come with two
black wire, I have no
idea how to connect with ceiling light wire and ceiling wire.
Please help.

Thanks
