Rear-View Mirror - Power Availability without Dimming/HomeLink?

[enz1ey]

I just got a 2017 CX-5 Touring, and I really want to install a dash cam because my life is generally filled with bad luck. I've seen where people are using the Invisicord to tap into the plug on the back of the rear-view mirrors equipped with auto-dimming and HomeLink, but is there any power access if you lack those features? I know there's that black sensor box behind the mirror, does anybody know if there is access to power in that box anywhere, regardless of package?

I have installed a few homelink mirrors on Mazda cars. They usually have a plug that taps into the wire harness in the A pillar on the driver side.

Thanks guys, this pretty much answers my question. I was hoping there would already be a harness/plug in that black box, but oh well. So I guess I'm just going to end up running the camera power straight to the fuse box after all.

Thanks again!
