You might want to stop in to the dealership and just ask them if they can give you a set of re-prints of your service visits "for your records" as you can't find the original ones. Rely on what they documented that they did... Here's the simple plug-in I bought off of Amazon... https://a.co/d/01xDUz1z I was able to use that cheap one to track engine data as part of troubleshooting I was doing on an issue in my previous truck. It took some time to figure out how all of the data fit together, but I brought my data and theory to my mechanic to verify and he agreed.
