3rd cable might be the traction control. I think that is a separate motor/cable to pull back the throttle in low traction situations regardless of where your foot is on the accelerator. So the f-body might have 3 cables, accelerator, traction control, cruise control. My car has 2, I don't have traction control(ASR) but I do have cruise control.
