What’s is this???
I have a 88 lariat, and would like to know what this component is which is next to brake booster. It looks like a vacuum pump, but not sure. What is it, and what does it do???

Yes, many carb vehicles have cruise control, and that servo was used from the late 70s until '92 (on F-series).

I was looking at it yesterday. Just looks like it needs hooking back up to vacuum port, and keep the cable piggybacked on throttle cable. I did notice the original vacuum can at front had originally imploded, sucked itself in, so must of had an original problem

There is no cruise problem that could cause the vacuum reservoir to collapse. It gets full manifold vacuum all the time. Either it rusted in a very even way so that it became too weak, or something mechanically crushed it (like something stowed under the hood, or a collision).
