Rear View Mirror Sensor
The nice feature is that this mirror doesn't need to be strapped to OEM mirror and can be mounted "in place" of OEM mirror.
The only 2 sensors on the OEM mirror: 1 sensor in glass for rear traffic bright light dimming. (no longer a concern with Digital Camera) and 1 sensor in the Back plastic of Mirror. I assumed and read a few posts indicating this was the Auto Bright Headlight sensor for Auto Bright feature. My original thoughts were to move sensor to new digital mirror, via a small circuit box or maybe in the mirror post housing.
Although this evening, I noticed with Auto Brights were operational, I could place my finger over the sensor and the Auto Brights continued to function properly: Brights going On & Off with Traffic.
Does anyone know what the Ft Sensor does on the mirror's rear plastic housing?

I saw the 2021 post… maybe rain sensor or lane assist.
it’s not lane assist, that’s done by cameras.
Not sure about rain sensing wiper sensor… thought that was in the head behind mirror mount?
If so, that’d be a simple one to relocate.
I’ve read "rain sensor" several places but tend to disagree because the sensor is always frosted white, not clear or optical. Frosted white is to diffuse light which would make detecting rain drops difficult.
Came across a great set of posts that makes much better sense to me. The ambient light sensor is normally a frosted diffused cover to collect surrounding light average… not a focused light. The Mirror Glass side sensor is more clear to capture a more focused light such as headlights. The 2 sensors work together to determine the auto dimming feature of rear view mirror, helps determines when it’s dark with a significant difference of light.
So, as a benefit I don’t feel any features are lost replacing a Ford rear view mirror, since the only feature in the OEM mirror is the auto dimming mirror. The Wolfpack mirror will auto dim its digital screen and not impacted by rear headlights.
I’ve always questioned why Ford doesn’t include a digital mirror like other Brands for more functionality. With the Wolfpack being able to mount in place of the OEM, and adds 3 camera views, GPS, 3 Recording cameras, etc makes an easy transition without messing up features. It would be much more challenging to replace if mirror contained several features.
I've also read that the wolfbox lacks a sensor to auto-dim itself, but I've not driven around at night just yet.

That adds a new variable to the modification... I was looking at your photo... can you send a little closer pic of the circuit board.
It looks like forward sensor is directly on the board... I was pondering the Rear view mount enclosure, the large plastic housing on windshield.
Edit - Add on...
You indicate for the first few minutes the dash instrumentation is dark. Does that mean it adjusts after a few minutes? Or are you manually adjusting?
On a different note... I just received my Wolfpack... too cold to install now outside.
How do you like it... camera mount, did you see / get the nice little snap in camera mount for back window?
On Etsy... great low cost mount that places interior camera perfect.

That etsy mount is great. Clean. I have a camper, so the rear cam is mounted all the way back there. So far, the wolfbox seems like a great solution to a blocked OEM mirror

The Etsy Mount is super, I ordered 2... very well made. I plan to mount the Wolfpack camera and my primary VanTrue 4 camera system... clean side by side setup. I have a US Flag decal on sliding window... cutting a small section from top stripe for cameras keeps it very clean. Easy to remove as well.
On your StarLink... I don't use but I've seen a mount that fastens to rear section of Sunroom pane. Faces skyward through glass. If I recall correctly, it's a suction cup glass mount.
Side note... when on Etsy... In search, enter Super Duty truck... you'll get several nice ideas. I found a handgun mount for Inner Drivers side console storage at your calf. Very clean, looks factory and on correct side for access. Found several door mounts but wrong hand & too high to lift if needed quickly. Several for Center Console, also a clean Magnet Clip for inner console as another option.
I stumbled onto the Wolfpack via this YouTube.
He moved up to Tri Pro for 3 camera setup.
On RV… his Cab Rearview, then 3rd Camera on Rear license or Bumper with disconnect. When RV, he changes to rear camera on RV and just swaps the connection at box.
I got the TriPro too, however I'm mounting the "bumper" camera on the roof of my camper, so I can quickly check clearance as I'm passing under trees, garages, etc.
I'm harvesting the electronics out of my (removed) tailgate for reinstall into my fabricated camperbed, so I can regain factory backup cam functionality.
Still need to mess with the rearview mirror circuit board and update this thread. Been busy welding up a complicated bracket to mount an ARB compressor between my fuel tank and transfer case.
Also, you can run the wolfbox (and Valentine 1) off the OE rear view mirror power supply. Makes wiring the Wolfbox a lot more straightforward that fuse tapping.
Do you wear glasses or progressive lenses? Are you able to focus on the digital display?
If Wolfbox would add a wireless backup cam capability for RVs that would be perfect. I use a Furion knockoff that works great but with the extra screen and also a FitcamX and the OEM mirror. One Wolfbox for dash cam and backup cams would be perfect.

So if I'm tracking with ya... you're retaining a light source for the Rear (backside facing windshield) sensor. From the looks, not concerned about the Mirror glass side sensor?
Haven't Gotten there yet... too cold to play with plastics in driveway. I'm visualizing similar with it inside a small blackbox or even tucked up in headliner with light sensor exposed.
To retrace... you were saying it does react to light but slower when mirror disconnected? Did that train itself faster over short time?
