I saw all the praise for the Ultimate 9 on this forum so I tried installing my throttle controller from ultimate 9 and it throws several warnings and I have no power at all. I contacted the company and they told me to leave the vehicle off 10-15 min before and have the key at least 20' away from the truck during that time and during install. I tried this several times as well and the same issue persists. Anyone have any advice?
