Mine basically crumbled when I did the replacement 3 or 4 years ago. It’s been held with a zip tie ever since. I did replace the zip tie with a new one this year when I went back in to do valve covers.
You may find what you’re looking for here. Most likely it’s part of the main wiring harness for the engine.
