My mother in law recently purchased a 2014 Toyota Corolla L and then realized that she didn't have cruise control.
Since my wife and I have been so happy with our 2005 and 2010 Corollas, I felt like I needed to fix this problem ASAP since we strongly encouraged her to buy one.
Here last car was a huge piece of crap (*cough* GM Oldsmobile Alero) that gave her and us lots of headaches.
So I installed the cruise control stalk in her car and took lots of pictures of the process. I put up a gallery with instructions on my personal travel site.
Here's the link to the DIY guide with the cruise control stalk part number -
I hope someone finds it to be useful. I know my mother in law was super excited to finally have cruise control again.
