Your new timing cover should have a cam position sensor and there is an adapter harness that will adapt the connector for the cam position sensor (3-wire) to the engine harness (4-wire): https://a.co/d/eobRAnXOn the non-VVT cam and timing cover, there is nowhere for that plug to go. Not even a dummy plug. So currently it's just tied up with the rest of the harness.
My new timing cover did not come with a harness. It was just the cover. I had to transfer over the harness and the harness bracket (which I modified) to make it work.Your new timing cover should have a cam position sensor and there is an adapter harness that will adapt the connector for the cam position sensor (3-wire) to the engine harness (4-wire): https://a.co/d/eobRAnX

If there are, they're subtle. Like nothing to the point that it feels like it's gonna die. It will rev up a little at times, and it sometimes "catches" when I first accelerate. But it's mostly just a very uncomfortable idle.any miss fires at idle?
I've looked through this whole thread again and haven't seen where you've said which cam you went with. If it's here and I still missed it, I'm sorry for the hassle.

I’m asking because any aftermarket cam needs to be tuned to run well, especially at idle.
I have a professionally-made tune file for the cam motion stage 2 truck cam in my 2012 6.2 L. You’re welcome to it if it would be helpful, if you can get a copy of HP tuners and the MVI3 device to work with.
Further investigation follow up:
It doesn't really feel like a miss. My neighbor (a retired airplane mechanic) thinks it sounds like a vacuum leak. Every video I've watched to test for that has an admitted risk of causing a fire...
Any tips on how to find a vacuum leak? I've looked for obvious cracks in lines. Slightly wiggled lines at the connections. Nothing changed. Short term trim levels fluctuate between negative and positive percentages, but never more than 10% either way. No clue if that is normal.
