I purchased the 12654088 ECM for my 2014 Chevrolet Express, and I’m really impressed with the quality and how smoothly everything went. The unit came VIN programmed and ready to install, which saved me a lot of hassle. Shipping was reasonable and arrived sooner than expected. The seller was also quick to answer my questions when I needed some clarification about the process. Highly recommend!
