Cable ?'s

I only have the cable with the red on it. I thought it moved with the pedal but maybe it doesn't? Is there another cable I forgot to hook up or am I just thinking too much? If so where is this mysterious cable?

FYI my cable has the red but it also has a barrell on the end of it which is used to mount inside the throttle spindle...not the external nub thing. Do I have an integrated cable or something...? WTF.
