Adding Cruise Control

I used to be content without cruise control but after my company upgraded my work truck i really realized how much I miss cruise control. So the question I now pose how hard would it be to add? What parts would I need? Anyone actually done it?

someone may add to this list, but you will need a turn signal/wiper/cruise control switch, speed sensor, regulator, and servo.

You will need to replace the existing switch.

You will also need a two piece speedo cable. The speed sensor connects between the two speedo cables, behind the dash cluster.

The regulator mounts on the lower dash panel under the steering wheel.

The servo mounts in the engine compartment and operates on vacuum to control the throttle.

Oh, and also the wiring harnes for the regulator.
