I’m really happy with this ECM for my 2004 Dodge Ram Cummins. The unit arrived quickly and was truly plug-and-play, making installation a breeze. The communication from the seller was excellent, and they had it programmed perfectly for my VIN. This saved me a ton of money compared to dealer prices, and everything has been running smoothly since the swap.
