I changed out my mirror on my 2017 to a Smartbeam with Auto Dimming, p/n: 68295862AA and it worked perfectly!
Thank you for the advice!

I have a 2018 Ram 1500 Express. I found an auto dimming mirror with auto highbeam dim on ebay. The auto highbeam finally appears in my light setting after 2 days of doing drive/ignition cycles. But it does not work, as when I push the stalk back, I get no message that the auto dim is working in the cluster. The rear mirror is getting power as the red light is on.

I added all the settings in the alfaobd word document of settings. One other strange thing is that the autodim app (for the rearview mirror dimming) appears also in the 8.4 apps, but does not work either. Lastly, I added a humidity sensor up there too, since that was the last thing I needed to do for the ATC, and does not seem to work. In Alfaobd check, all 3 items (auto dim, dimming mirror and humidity sensor) have error in that they have lost communication with module, not present. I know it is getting the linbus as I ran another wire up there.

Any thoughts? I dont think its a bad mirror as the humidity sensor is not working either.
Did you and Mpgrimm2 ever figure out what the problem was? I’m kind of running into the same issue. I just bought an auto dim/auto highbeam mirror out of a 2018 and a harness that has plugs for rain sensor, humidity sensor and atc though I don’t have those, I figured having the extra plugs won’t hurt anything. I installed them into a 2021 ram 1500 classic that I upgraded to the 7” evic and the 8.4 radio. The mirror works but I don’t think the auto dim nor the auto high beam are working. I used alfpha obd to enable the features and the soft keys on the radio, when I press the auto high beam option in the settings I do not get a message on the evic that they have been turned on or off, and the auto dim won’t engage either when I press that. I’m doing this during the day so I’ll come out tonight to see if it works, but I don’t have high hopes for it. If you could let me know what you did to fix your issue, I would be grateful, thanks.

2018 Tradesman, 8.4 upgrade, Single Zone ATC, (Dual-zone eventually) Props to @Mpgrimm2 for making that smooth!

I see I need a mirror -
-2018 PN: 68342284AA (Assist/SoS/UConnect "Connected" AutoDim w/SmartBeam)

The harness is the question.
I see a 1500 harness with the bits to match the mirror above (Auto dim, smart dim etc) -
- PN: 68343002AA - 2018 AutoDim Mirror Harness (no mics) W/humidity Sensor (atc)
- My Mics were in the headliner already

Can my 2500 use the 1500 harness PN 68343002AA?
I want the rain sensor plug for future options.
I'm assuming Yes as it seems so much is interchangeable, but I know there is a difference in humidity sensors AC compressors... And that 1500 harness specifically says "humidity sensor"

I wouldn't....

Does your truck have cab lights or not?

If so use the 17 ram 2500 harness with cab lights....

If not... We'd need to find the VIN off a 2017/18 2500 Laramie/limited w/o cab lights (plus rain sensor) and use it's Vin to look up the harness PN with @AllMoparParts

My truck does not currently have cab lights
I assume a harness with cab lights is ok, I just won't use them as I don't have them currently.

I cruised Autotrader for 2018 2500 with the options I want -

Found this VIN 3C6UR5NL8JG179352 2018 Ram Laramie
https://www.chrysler.com/hostd/windowsticker/getWindowStickerPdf.do?vin=3C6UR5NL8JG179352
CONVENIENCE GROUP -inc: Rain Sensitive Windshield Wipers Auto High Beam Headlamp Control
No Cab lights
AllMoparparts points me to 68309102AA for a 2018 Ram 2500 Laramie
I'll have Benny verify

Can I use the harness with cab lights for future-proofing?

@HighShyGuy yes you could use it...
Only issue that might occur is I'm not sure how big the cab light connectors are and if you can squeeze them under the headliner without going through the roof.

Edit: found a possible picture of it at CarID... 68309102AA

Looks like it has cab light connectors... Wish picture would come in clearer so I could see everything in detail.

Benny confirmed part 68309105AA is for a 2018 2500 with dual zone ATC, rain sense, auto high/dim, with NO cab lights.
I have it on order and will update when I get it installed.

How hard do I twist to get the old mirror off... I really don't want to break it off the glass...
I see it says counterclockwise, but man...

I haven't done the swap in about 5yrs now...
Here's a video... start at 2:20 mins in the video.

I'm looking to update my '13 3500 Big Horn to a mirror w/ Auto High Beams. Truck currently has the 911/Assist AutoDimming Mirror. Should this be as simple as installing a new mirror (911/AutoDim w/AutoHighBeam Mirror: - 68096094AA) and using AlfaOBD to activate? Is a new harness needed?

If you already have a factory 8.4 (or 5.0") radio with only a BuCam that displays on the radio, then it should be a direct swap and you should have the correct harness for the swap.

If you have BuCam displayed on the mirror ... It's the wrong mirror harness/connector and the new Auto High beam mirror doesn't have a BuCam display... & 2013-15 8.4 radios Will only display one video input BuCam or Cargo (default if installed) requiring either SW v17.11.x or a 16+ 8.4 radio to display both.

Thank you. My BU camera displays on the 8.4" radio. I'll search for a mirror and try it out.

It was as simple as plugging in the new mirror, and activating with AlfaOBD. Works great. Thank you for the guidance.

I can confirm part 68309105AA is the needed harness for a 2018 Ram 2500 tradesman to add rain sense and auto-high beam.
This harness has high-beam and rain-sense plugs WITHOUT cab lights.

Do I need the 8.4 radio to enable the auto-dimming and auto-high beam features? I have an aftermarket radio and I was wondering if a can enable those features with alfa obd
