help identifying connection

Hey all,
I installed a 4barrel carb on my 69cougar/351w engine/c6 transmission, there is this connection that goes from the old carb to the c6 transmission. but now i don't have any were to connect this to. it looks like it connects to the throttle similar to the throttle cable.

i dont know the name of it and what it does, any input would be appreciated as to what to do with it / where to connect it

thanks again.
