What kind of plug/wiring does it use?

I was cleaning the passenger side door sills yesterday and pulled the plastic trim piece up. Found what could only be the Backup Camera wire running on-top of the main wiring harness.

I want to shift/split the camera to input to my JVC AVX820 Headunit...and still show in the Rearview mirror. But I have no idea what kind of plug/wire goes to the Rearview.

I could pull it apart and look, but not really in the mood to go this route until it's time to plug into the headunit

TIA
