19 GMC 2500 3500 SIERRA 6.6 L5P DURAMAX DIESEL ENGINE COMPUTER ECM ECU 12694498

Here we have a good used engine computer removed from a 2019 GMC sierra 200hd. Should fit most 17-19 duramax trucks with the L5P engine only. Fully functioning condition but will need to be programmed to your vehicle. Make sure this will work in your truck before purchasing!
