Installing ATC & Auto Headlights but need a bit of help...
So I'm getting older and there are a few creature comforts I'm missing that I've had in other vehicles, those include ATC and auto headlights. I've done quite a bit of homework on the ATC and feel I have a pretty good handle on that. There doesn't seem to be much out there on the auto headlights though. A bit of background, I have a 2013 JKU Sport S that came with AC, rear defrost and fog lights. On the ATC side, I've found the following 3 threads quite valuable:
Upgrade-climate-controls-auto-ac-heat/
Cabin-air-temperature-sensor-location
Upgrade-heat-c-automatic-temperature-control
mattro, sircody, ATLJeepsTer among others did a great job of breaking down what was needed. In short, I needed the Sun sensor, the cabin temp sensor, the cabin temp sensor connector, some wiring and the HVAC control unit itself.
I've ordered and received the following:
Sun Sensor - 55111275AA (does both auto headlight and sun sensor functions)
Cabin Temp Sensor - 55111178AC
HVAC controller - P55111170AD (takeoff I found on eBay)
Once I got those, for shits and giggles, I tried plugging the cabin temp sensor into the sun sensor connector and it fit! This was important as there is no part number listed for a cabin temp sensor replacement connector. So now I've ordered another sun sensor connector for which a p/n does exist...68080566AA. While I wait for that, I've gotten a bit done on the install
1. The dash is torn apart to allow access to the HVAC controller:
2. I inspected the sun sensor area under the dash. You can see in the next picture there is indeed a harness running up there. Upon closer inspection (2nd photo) you can see the connector plugged onto a dummy clip molded into the underside of the dash. There are only 2 wires in this connector, the ground and the auto headlight wire. I will be adding 2 additional wires for the sun sensor. These will run to pins 9 and 10 of the blue HVAC connector.
3. I removed the dash panel under the steering wheel and inspected the nearby harnesses. As suspected, no loose connector is there as I have a Sport. You can see in this photo though that I did mount the cabin temperature sensor in place.
Once I receive the connector I ordered, I can start wiring this up. This brings me to my first 3 questions based on the following 4 and 16 way connector pin outs. My questions are in RED.

4. For clarification, here is the blue HVAC connector I referenced to. Notice pins 9, 10 and 16 are currently empty (bottom row).
5. While that's open for discussion, I drilled about a .750 hole in the dash for the sun sensor. It's tough to make a clean hole as the windshield keeps you from getting in there with a drill. I used a 90 degree pneumatic angle grinder with about a 1/4" drill bit in the collet. That made the initial hole. Not having anything larger that would still fit my grinder collet, I put a .685 countersink in there. It made a mess with chips flying all over but I ended up with a hole that the sensor fits snuggly into. Those are the next 2 photos:
6. That is about as far as I got. I did mount and plug into the new HVAC controller unit. It powered up fine and as mattro noted, the rear defrost button blinks with no other function for about 30 seconds. After that, it does begin to function more normally. Manual mode for heat/AC and fan level work fine. The rear defrost works fine too. Obviously, until I wire up the 2 sensors, Automatic mode doesn't work as intended.
That's it for the ATC part, any help you all can give me is greatly appreciated!!!!!!!
This now brings me to the auto headlight feature. The reading I've done on this is limited as there isn't much out there. Combing through online mopar part sites, what I can gather is that the sun sensor and turn signal stalk need to be replaced. The sun sensor I've already identified above as 55111275AA and as I stated, I confirmed the wiring for this runs into the HVAC controller as required in the 16 way pin out above. The other item that is obvious is the turn signal stalk. I believe this to be p/n 68015101.
Question 4 - can anyone confirm this is the correct part number for the stalk?
Question 5 - Are there any other parts required that I am missing?
Question 6 - if I replace the stalk with this new part, will it just work or will I need a dealer to flash a sales code of some sort into the TIPM?
Once again, any input is greatly appreciated!

Kevin,
I did not get as far as you did, and I sold my JK in August (4.00 gas + living downtown = very thirsty and expensive Jeep with a never ending appetite for fuel) I think you are well on your way, and wiring is the key. I didn't ever get the in cabin temperature sensor wired so I'm afraid I can't help, except to offer up this:
Ask 11rubiwannabe. He and I talked on the phone about this upgrade, and he was going to try to wire his up.
Hope you figure this out,
Matt

Ac not working
Hi ThereI bought a canadian spec JK 2016 model. It didnt have an ac in it. Hence we thought of adding ac. Bought & fixed all condensor, compressor, pipings, evaporator & even changed the fuse box. But still the ac is not working. The Jeep didnt have a sun (as attached). Is it necessary part of the AC. Could you please let me know?

Anything on auto headlights?
I know this is an older thread but I’m curious if anyone ever figured out installing auto headlights on a US Jk. Be a neat feature to have if it’s not too complicated
