I recently purchased the 20325253AO ECM for my 2004 RAM with the 5.9L Cummins, and I couldn’t be happier with the entire experience. The unit arrived quickly, and the fact that it came VIN programmed saved me so much hassle — it was truly plug-and-play. Throughout the process, the seller kept me posted with updates and promptly answered all my questions, which gave me a lot of confidence in what I was buying. Since installing it, my truck has been running smoother than ever, and I’m very impressed with the quality of the repair. Honestly, this was one of the best online parts purchases I’ve made.
