Buy the one for the Liberty from Mopar. You can find them for $250 off of eBay and install it yourself! Thats what I did and it works flawlessly. It took about 3 hours to install but every minute of it was worth it. The instructions are so easy to follow and everythings designed for the Liberty. Its got programable light flash/horn flash, programable run times, Hood saftey switch, starter kill, adjustable idle speed. I love it!
