David, I am not positive on this, but pretty sure the EGR Tuner from egrtuner.com is designed for DDEC IV & V engines only. The instructions that came with my kit were for those engines and I do not remember any other engines on the site when I ordered. If you still want an explanation of where and how to install the kit, let me know. I'll be glad to help. PS, the installation was fairly easy, even for a klutz like me, once you grasp the concept.
