I recently purchased the 20325233AG ECM for my 2004 Ram 5.9L Cummins and couldn’t be happier with the experience. The shipping was impressively fast, so I had the unit in my hands much sooner than I expected. Installation went smoothly since it came VIN programmed and truly was plug-and-play; no guesswork involved. This saved me a ton compared to the dealer’s quote, which was astronomical. The team’s communication was clear and helpful throughout, making the whole process stress-free. Overall, a top-notch service that I would recommend to anyone needing an engine control module replacement.
