Kyle - I'm determined to get Auto Climate Control in my 2015 Silverado I just picked up.   Thanks for the detail on how you were able to accomplish this.  I have everything on order now, down to the molex connectors that are needed in your description above.  What I cannot find is the wiring diagram of the X1/X2/X3/X4 connectors into the Control Module.   Can you please let me know where you found that so I can grab it .   BTW, my new control module 13591693 has J1,J2,J3,J4 not the X....   I assume your had it as well?  And the driver upper and lower duct temp sensors - where did you mount them?  

 

You have to find them in the upfitter electrical wiring manual which is free online, the J should correspond to the X fittings, they will just be listed as X in the manual. If you give me some time I can try and find the specific wiring diagrams related to the connectors.

 

Not sure if this link will work, but this is it:

Hello Kyle,

I am interested in the HVAC mod for my 2017 WT Double Cab (midnight edition).

The truck has the light sensor in the dashboard. Would I need the additional sensor?

Will it mount along side of the existing sensor? Also I have purchased the HVAC control

for a 2017 High Country  #84173748 w/ATC. I installed it and it has full "manual function" with

the exception of the last blower Icon being active on the IOB 7" screen. It looks like the Dash Sensor

and Temp sensor are the same Part Numbers as your install. The ATC Module I am purchasing is part number

84237325 also for a 2017 High Country with ATC. Would you be willing to assemble the required plug ends and terminal

wire harness for me. I have trouble with the crimping operation due to nerve damage in my hands. I will of course pay

 for everything and your time. I have successfully installed the "Heated Wheel" upgrade along with Pgambola wire harness.

My next mod after the HVAC ATC will be the conversion from my "IOB" 7" infotainment center to the "Denali Cluster". It looks like

I'll have to replace the entire HDMI, Screen, Radio etc to realize the Denali upgrade. 

Also are there specific markings for the temp sensor for the ducting such as a circle or molding mark for install?

Thank you for any assistance and information you are willing to share.

Love your engine mods on your truck and your vids. I sadly have the lowly 4.3L in my truck that will stay stock.

Has anyone else completed this setup. Just try get some more detail on what to do or some pics. Thanks.

Gm 23281485 ac wiring harness. I wonder if that has the sensors and just be a plug in play option to make it work.

First off want to say thank you for all this way to knock it out of the park. I have a 17 Silverado are the part numbers the same? I know gm likes to use the same modules for what seams to be decades but when I'm looking up the part numbers I see that they seam to end at 15 for year range
