Can I add cruiz control to an "02 3500 van ?

I have an '02 dodge ram van 3500 15 passenger version that I use for long trips. Is it possible to add cruiz control, maybe from a truck, preferbly from the local "yard" or my second choice would be an aftermarket source. Besides the vacuum can and second throttle cable what is involved ?

I used a universal kit that was actually very simple. A tiny magnet was installed on the driveshaft next to a speed sensor. Other than a vacuum can and throttle linkage it has a simple wiring harness and a controller that mounted either on the dash or the turn signal stalk.

MajicRat,
Do you remember the name or the source of this kit ?
I would like to get this done before spring.
