I have a 2016 se edition that did not come with auto headlights. I fished the sunlight sensor wire out of the dash and replaced the front dash with a new one that has the sun sensor in it and plugged it in. Then I checked the ac controls and it already has the other end of the connection plugged into it. Then I replaced the light switch with one that has auto on it. Then I used alfaobd to enable the twilight sensor and ran a proxy alignment. Does anyone know what else I could be missing to get auto headlights working? Is there something else in alfaobd that needs to be done? Or another sensor I'm missing? I don't have the rain sensor or the smart beam high beam sensor but those shouldn't be required as even the donor car I removed the switch and sensor from didn't have those.

The sun sensor I used:

Update: I got the automatic headlights retrofit working. Turns out the ac control module that came with the car with the sensor plugged into the back had no pins soldered in it. So I had to find a junkyard car with automatic headlights to swap out my ac control module with it and now the twilight sensor is recognized and lights are turning on and off automatically.

I am also looking to install auto lights in my 2016 dodge dart as well. Did your car already come with the wiring needed for the sensor or did you have to purchase that separate?
The wiring was already there but the dash side was really hard to find cause it's taped to the underside of the plastic and could barely reach it. You should be able to tell if yours is there by pulling the ac control module out and if that side of the wiring is there like mine then it was already plugged into the ac module and you know you should be able to find the taped wire in the dash through where the center speaker would be.

Ok that’s good news. So I’ll get the sensor and the switch for the install. By ac control module you mean the dials in the front below the radio right? Do you know what part you had to swap out in the ac control module to have it work?
Yeah it was the module that has the dials in the front. The entire module had to be changed. Here's the module front and back and the 4 wire sensor cable. It had the port that it was plugged into but there were no pins inside to complete the connection. Here's the part number for the one I got that has the pins if you have to order it but it's probably gonna be cheaper to get it from a local junkyard if you have one available. The sensor is also not just the sensor cause it's built into the front dash plastic even though it looks removable it's all one piece so it's also best if you can get that from the junkyard so you don't have to pay shipping.

Or rather I should say that the sensor itself is removable but the surrounding rectangular area that's meant to hold it is not. So if you want it to sit in like the factory then you'll want the whole front dash plastic that's meant to hold the sensor. The module itself removes really easy by just putting a trim removal plastic under it and pulling it out cause it just snaps into place.

Excellent thank you! I used that part number and found a matching ac control module, should I need it to complete the connection. So all that’s left is the front dash plastic that holds the sensor in place. If you have a part number for that or if you know what that piece is called that’d be sweet. After this is all installed, I have to proxy align the system? Is that necessary or can I do without that step? Thank you for all this information, it’s been incredibly helpful.
I see this part number from an ebay sale so I'm not sure on accuracy cause when I search these parts I only get the two ebay sales. Maybe @alpinegreenneon can verify part numbers.

Also this part number from earlier revision

Before you run proxy align you also need to enable the sunlight or twilight sensor in the bcm, I forget exactly what it's called. You also need a new headlight switch that has the auto setting if you haven't sourced that. There are two different ones. One with and one without fog lights.

I highly suggest going to one of those pick your own parts places for these though cause you can get the plastic dash panel piece for about $15-$20 and the sensor for the same or less. Maybe even a package deal if you leave the sensor attached to the plastic. All for less than what ebay wants for just shipping. When I went to about 15 cars there were about half with this sensor in them so there is a good chance it will have the parts.

Activate the sensor in the BCM? Like add a fuse in the location that it would normally sit or do you mean something else. BCM is the body control module I think.
Using an obd scanner like obdlink mx+ with alfaOBD software to connect to it. You would then open the bcm module in alfaobd and reconfigure the car to tell it the sensor is installed and you have that feature. Then the proxy align after.

I am willing to pay $50 for help
I've never seen anything like that. I've not tried doing a custom proxi before. I've only gone into the bcm menu and enabled or disabled setting from menus and then run a proxi align. Are you trying to enable automatic headlights or is this for something else?

I want to import custom configuration. Importing dart code may solve all the problems I encounter.
Would I have to use that software you were using previously to obtain this code? I don't have the car currently cause it's my kids so I'd have to wait for later when they return to do anything. But programming by codes like that sounds like it could cause other issues since we likely do not have the same car configuration overall. I've also made other changes to my car configuration.

I receive an error when I try to connect. Not sure if my laptop I'm using is not compatible with the software or something else.

The Bluetooth OBD baud rate is set to 38400 in the computer
1. Go to Adjustments
2. press ctrl+alt+c from the keyboard
3. Multiecuscan will open a window with title “Custom PROXI”. Be very careful here not to delete or change something!
4. You should see a box with many bytes of data (this is the complete PROXI configuration)
Ok I'll check both the .net and the baud rates. It will take me until tomorrow night or the next to be able to get the car back again.

Are you sure that the sensor cable is not connected to the air conditioning control module, but to the panel
Yours might be different cause yours seems to have the climate control ac and I'm guessing the lcd screen for radio and other controls. Mine was basic and did not have lcd and all manual ac. For mine it plugged directly into the back of the ac control module with the dials on the front. The wire colors were the same on both sides and was a 4 wire connection. Your might have just a module that it connects to that's inside the dash.
