Here we have a good used engine computer removed from an 04-05 Duramax 2500hd with the lly engine, fully tested and functioning however there is a small chunk of the middle plastic connector that is broken. This will fit gm trucks with the LLY Duramax engine ONLY. Please ensure this will work for your application by viewing all of the photos, This may require programming to your vin. These are non returnable. Any question please just inquire.
