correct. I did precisely that. I have a factory 8.4 with nav. I recommend their cable. It is well made and a perfect fit.

I planned on covering up the passenger up/down buttons with some black vinyl.... outta sight, outta mind.
How manytime to install? It is possible to use another method without obd genie? 200$ for just one function. the price is very to high from obd genie.

When you program the Genie it also reads your VIN and locks it to that truck. You could buy the Autoenginuity tool for more but it also does more. I went with OBD genie because the AE tool corrupts the brand. I also have someone close by that is a great help that has one.

MPGrimm and I have been working on figuring out how to convert our trucks from manual temperature control to automatic temperature control. We have made enough progress to prove that it can be done and want to share what we have learned with everyone.
This is a pretty easy and inexpensive mod in terms of parts. You basically need to buy a cabin temperature sensor, a connector, and some terminals and put it all together using an existing 8.4 conversion harness. The trouble with this mod, is that the feature has to be activated in the BCM. I used my AutoEngenuity tool to activate the feature, but unlike activating some other features where it was a smooth process, this caused corruption of my trucks “vehicle brand” which caused the 8.4 Radio to loose it logo and themes. I have not found a way to correctly reset the brand. If you have the AE tool, and want to try this mod, please be aware of this issue. I have not encountered any other problems with the truck due to this issue, but proceed at your own risk.
Anyways onto the mod:
Parts Needed:
(1) 55111178AC – CABIN AIR TEMPERATURE SENSOR
(1) 1-929170-4 – 4 WAY Connector Shell for Temperature Sensor
(4) 963715-1 – Female Terminals for 1-929170-4 (Temperature Sensor Connector)
(2) 1123343-1 – Female Terminals for 1318917 (HVAC Module Connector
Conversion Harness Modification
You will need to pin two new wires into pins 11 and 12 of the HVAC module side conector of the conversion harness. These wires will run from the HVAC module to behind the drivers side kick panel where the Cabing Air Temperature Sensor will be located (more on that below). I made my wires 80" in length. You will also need to splice wire # 2 for fused ignition power and wire #14 for ground. These will run to a new connector for the temperature sensor (1-929170-4). The following schematic shows how to wire it up.
Here's what my conversion harness looked ike after adding the temperature sensor wiring. Notice the new leg off of the harness. It is shown with the sensor attached.

Installing the Temperature Sensor
The temperature sensor is located behind the driver side knee kick panel. You will need to remove the panel and install the sensor.
1. Remove the two screws at the bottom of the panel and then pull the panel off.

2. Install the sensor.
IMG_0811 by Deere Guy, on Flickr
3. Route the new leg of the conversion harness over to the sensor and plug it in.
4. Reinstall the knee kick panel.
Activating with AutoEngenuity
Note: Do this at your own risk. I am not responsible for anything that may happen to your truck as a result from performing this modification.
1. Connect the AE tool to the truck.
2. After selecting the truck, connect to the Body Control Module.
3. Select the "Test Onboard Systems" tab
4. Select Module Configuration from the drop down.
5 . Select "Initiate"
6. Accept the warning message.
7. Using the arrows on each side of the done button, scroll down to "vehicle config 3".
8. Press Done.
9. Using the arrow buttons select" HVAC Config" press Done.
10. Using the arrow buttons select "Dual Zone ATC" and select Done.
11. Wait for the write to complete.
12. Reboot the radio by pressing both knobs simultaneously for a few seconds.
13. Repeat the above process but this time select "Single Zone ATC"
14. Reboot the radio again.
As you can see in the picture below, I have mine set for a single zone automatic temperature control. I am using a standard MTC bezel, and just using the "Auto" button on the radio to switch it into Automatic mode.

i have a question. i would buy a sensor and cable from you.
Where to buy this cable?
also, what do you say by:
1. Connect the AE tool to the truck.
2. After selecting the truck, connect to the Body Control Module.
i find old AETOOL 1.3. What is your version and waht is the plus used for connecting to the trucjk? Please explain more.
Regards

If you would like a harness, please send me a PM with your information and I'll help you get one ordered.
As for the AE version, the current version is 15.20. Seems like you have a really old version. You would need the AE ST-06 scan tool that plugs into the odb2 port and the laptop and the EI-04 Chrysler enhanced package. You can find all of the details for AE @ https://www.autoenginuity.com/products/scantool/. I would hazard to guess that version 1.3 will not work.
It's a lot less expensive with the Genie and it doesn't corrupt your BCM.

Just added the Automatic Climate Control to my Ram R/T and I couldn't be more pleased. It is an extremely simple install that works great!!! Special thanks to DeereGuy for a very professional wiring harness, and also to OBD Genie for making a simple to use programmer that does the job!!! Kudos to all involved in making this work...

quick question
I've removed the kick panel and the sensor is there already and wiring is attached.
Should it be enough just to flush the BCM?

If you are confident the wiring is in place and correct, then yes. Just be aware of the issues activating it as mentioned in the OP.
(Did your 16 SLT EcoD come with a dual zone ATC and 8.4 radio? Not sure why you'd have the wiring otherwise)

Take a look at the connector that plugs into the HVAC module and see if pins 11 and 12 are populated. If they are you should be good to go. The picture below shows the connector not populated with those 2 pins.
