Josue N. United StatesPerfect when you follow instructions
I ordered this to remove the check engine light after replacing my mirrors with aftermarket ones that didn’t have sensors. It was easy to install and works great. I didn’t unplug the battery like their video said to do so and my temperature reading was off. And I was getting warnings about driving careful while on ice. After unplugging the battery and plugging it up again it reset the computer and everything works great

The part worked flawlessly, after installing mirrors CEL was on due from the sensor missing. Added this in mirror CEL cleared itself (2017 2500hd duramax)
