Default Automatic Compression Release

This thread is more for confirmation than anything else.

I have read that all 103 engines (except for a few models) come stock with Automatic Compression Release valves. This is not just CVO models, correct?

I ride a 2012 Heritage. In the picture below, is the arrow pointing to the Automatic Compression Release wiring harness? If not, what is the arrow pointing towards?

I appreciate the input.

I believe that is the temp sensor.
I think the auto releases are on the top of the head.

Much abliged for the prompt reply.

I looked up info on the engine temperature sensor and that is what it is. Also explains why I couldn't find a similar part on the rear cylinder. It would make sense that the ACR wiring would be near the valves.

Thanks again for IDing it for me.
