There are several ways to do this, but this is the one I chose. Hope you enjoy the write up. It was done on a 2005 Liberty with a 3.7.

I would not recommend doing this unless you are familiar with programming and electronics. That being said, here are the simple instructions that assume you know that stuff:

1. Buy Arduino UNO
2. Buy IR LED
3. Download this software to it
4. Wire in the steering wheel signal (all violet in color and is the 6th pin of a 6 pin connector under the steering wheel) to Arduino analog input 4.
5. Attach and control the IR LED with the Arduino's digital pin 7. You should also drive it with a transistor circuit if possible (see site for example).
6. Power up the Arduino
7. Test and troubleshoot
