Welcome. Yes, the OEM heated grips are excellent although expensive. There's a thread on here somewhere suggesting Oxford or similar heated grips can in fact be connected into the OEM connectors and work the same once a dealer enables them. Cheers.
I have Oxford Premium grips wired into the Ducati OEM connectors behind the headlight.
It's a simple job, 4 screws remove the whole front end, 2 screws for the headlight. The wiring is tucked up inside rubber tubes on either side of the headlight and is labeled so it's ***** proof. There's also a switched live behind there, I used it for my GPS.

Edit: you do have to get the dealer to enable them, whether you fit OEM or aftermarket, then they work just like the OEM using the start button.
