No ease of installation

It is a high-quality part. However, if you go by the bag's labeling, you'll most likely be wrong. If you go by the meticulously labeled wires, you'll be wrong again. All these GMs were not wired the same, so this is not a plug-and-play part. I ultimately gave up after a few days of trying different things. In theory, this is a great part. In practice, it left significant gaps.
