25 GMC 2500 3500 SIERRA 6.6 L5P DURAMAX DIESEL ENGINE COMPUTER ECM ECU 12733910

Here we have a good used engine computer removed from a 2025 GMC Sierra 3500hd. Should fit most 24-25 duramax trucks with the L5P engine and maybe others. Fully functioning condition but will need to be programmed to your vehicle. Make sure this will work in your truck before purchasing!
