Will this mirror plug directly into my HR-V's existing wiring?

Yes – this is OEM spec, so it connects at the factory electrical harness behind the door panel. No adapters or rewiring needed.

Does the heating element work right away after installation?

It will once you've connected power and tested the switch. Run the heater for 30–60 seconds on first use to confirm function before closing the door panel back up.

What if the power-fold mechanism doesn't respond after I install it?

Check that all connectors are fully seated in the door harness — a loose connection is the most common cause. If it still doesn't fold, the assembly may have a defect; contact support with your order number.
