Do these mirrors use factory mounting points?

Yes. These are designed to mount at existing factory towing mirror locations on your Ram — no drilling or new holes required.

Will the heated element stay on all the time, or is it switchable?

The heating function activates through your vehicle's climate or mirror control system. Once wired in, you control it like any factory heated mirror — typically a button on the door panel.

What about the wiring for power and signals — is that included?

Mirror assemblies are included. Wiring harnesses and connectors are not confirmed — verify your vehicle's existing mirror wiring compatibility before ordering, or contact a Ford dealer parts line for the correct harness part number.
