Call Cat and have them do it and it will run you $3000. Just had it done by them. I wanted to install it myself but was too busy. Plus they have to hook the computer up to the tractor and change something. It is a module and a wiring harness that goes out the back end. The module gets put under the floor under the seat. This was on a 2002 MT 765.
