The part number you are looking for is in the description on that page.

I do have this installed on my 2021 Sierra and no issues.

I too am getting the same message almost every time I start the engine. This started maybe two weeks or so ago. It may be from a recent update or time or date related. For the auto stop/start issue, check out https://www.autostopeliminator.com/products/2019-silverado-sierra-autostop-eliminator

Sounds like someone either started the process of registering the tire pressure sensors on your vehicle or on one close to yours. Have them complete that process on yours.

Yup, got mine.

Depends on the vehicle. I was thinking of my wife's Terrain. I forgot but the purple one is maybe for Onstar and GPS. I do know that on my Sierra and the Terrain the gold connector is for XM.

You got the wrong antenna. The purple connector is for FM radio. The gold one is for XM

There is none. The flashers are controlled by the BCM.

It's been almost one year and it's still not fixed.

I have to agree. This thread has been going on for 8 months and no resolution.

You have everything reversed. What is on the left should be on the right and what you have on the right should be on the left. Swap the sensors around.

Can you show the other side?

Do not use the frame as a gound point. Run the ground wire from each light to the ground wire up front. Logically using the frame should work but I have seen posts on here and other forums many times about this sort of thing and running the separate wire fixed the issue.

This hapens when the steering wheel is turned all the way one way or the other when trying to start. This happened to me. It took quite an effort to get it turned enough to start.

You have to press the black tab between the two red portions in your picture and then pull.
