I bought the 20325233AB ECM for my 2004 Ram with the 5.9L Cummins, and the whole process was smooth from start to finish. The unit came VIN programmed and ready to install, which saved me a lot of hassle. Shipping was quick and affordable, and the seller kept me informed every step of the way. The truck runs perfectly now, and I couldn’t be happier with the quality and service.
