I was a bit nervous ordering an ECM online for my 2004 RAM, but this unit came VIN programmed and ready to go, which made the installation process so much smoother. The shipping was surprisingly quick and didn’t cost an arm and a leg, which I really appreciated. What stood out most was how the seller kept me in the loop throughout the whole process, responding quickly when I had questions. Once installed, my truck fired right up with no issues, running perfectly as if nothing had happened. It’s been a week now, and I couldn’t be happier with the quality and service overall.
