Well, as pointed out, there are no signs of any cruise parts under your 
hood.

The first two pictures here show it pretty well:

You are at least missing the pump, which would be on that bracket by the 
laster cylinder, the hose to the servo, the servo and its bracket, and 
the rod to the throttle actuator.

You also might be missing the wiring harness, the hoses to the pedal 
switches, and the control box.

Perhaps your car never had cruise and someone at some point swapped in a 
another set of stalk switches to replace bad ones?

It's a bit of work, but you could get a system from a dead car and 
install it.  The block diagram here:

Shows pretty much everything. just not exactly where it goes.  The 
Bentley has better location pictures, I think.
