Unichip X computer, almost new and with all its accessories: wiring harness, connector, and switch button. Programmed and ready, three switches: one for fast throw, the second for slow throw, and the third is original for F-series and fits the 4500 and other cars like Toyota, Cherokee, Pajero, and many more. Meaning, if you install it on an F-series, it's ready and doesn't need anything. If you have a little experience in installation, you can install it yourself. I'll send you pictures of where each wire is connected. It cost me 3400. Selling to the highest bidder. Serious buyers can contact me here or on WhatsApp.
