What is this?

What colour are the wires for the original connection in the cab?
And if I have this, why do I have a vac modulator on the RH side of the tranny?

that is the kickdown switch for the turbo 400 i think it has red and white wire ran to it.. the wire that goes down to the transmission is orange. if you dont have a turbo 400 you dont need it.. the turbo 350 and 400 both have a vacum modulator thats what causes it to shift .
