2002 express van oem cruise control

First time poster, I'll try to be brief. I have a 2002 Chevrolet Express 2500 Cargo van that I am converting to a leisure vehicle. 4.3 L V-6 with 1 ton rated auto tranny, 1 ton axles. What I hope to accomplish is to install the OEM cruise control system. The wrecking yards are full of cash for clunker vehicles now and these parts are very inexpensive to acquire. Aside from the visible parts such as the turn signal switch and the cruise control module I do not know what additional components I need to complete the system.    All help and installation tips are gratefully appreciated. I am retired so I have near unlimited time to devote before commencing this project. Thank YouSo many circuits, so little time!

Thank you for your speedy response. Of course, I have the cable connected at the top. No easy way for me! May I impose on your for the components that I will need to acquire? Please assume I know nothing, because really, I don't! I hope to learn the components, their function and location before starting the installation process. A real bonus would be if you had the GM part numbers as well, but I am grateful for any information sent this way. This is a fabulous venue! Props to those who share. So many circuits, so little time!
