The info on the website was a little misleading. For my Tundra and other Toyotas this is an in-line device that needs to be installed behind the speedometer cluster. Don't let that discourage your interest, the instructions were very well written and it was actually quite easy. Patience is important so you do not break any of the small clips. The programming portion took seconds once plugged into the computer, the software is very easy to use. So far, the device has done exactly what I needed it to do, adjust for larger tires. I double checked the calculations myself and everything is right on. Also, I have seen an increase in gas mileage of about 1 mpg, a nice bonus.
