2013 Tacoma rear view mirror Auto dim, temperature, rear-view camera, hooking up dash cam

I have a 2013 Tacoma, two-door, the rear view mirror is Auto dimming, temperature, rear view camera. I'm hooking up a dash cam with an adapter harness to the rear view mirror connector. How many pins is the connector?? 10, 12, 14, I've been getting different answers. Also is it easy to remove the rear view mirror just enough so I can hook this new wiring harness to the connector already in it? Any help would be very appreciated thank you

 

Look up info for Bob's Mirrors. They recently did a custom harness to let me install a mirror they had done for my 2018 Tacoma to be put in my 2007 Tacoma that had a different wiring hookup. He had me send a pic of the mirror harnes and I had a splice harness in a week. Not sure about camera stuff, but he would be a good place to start.

Bobs mirrors hooked me up with my 2014 Tacoma. Great and complete photo directions. And fast follow up for questions.
