These harnesses are not cheap due to the plug-and-play feature of them OEM connectors are not cheap. This also requires the purchase of the Seat Control Module to regulate the power going to the seats. It does work and I have been using it for about 3 weeks now doing some fine tuning to the programming to get it just right. PM me if you are still interested. I also do not have any extras built at this time it will take a little bit to get the parts in and build it.

I'm not sure if there has been confusion or not but I just want to make sure. My harness is for trucks that had heated seats from the factory and the radio/climate bezel has been updated to include auto-climate and the heated seats do not work anymore. It does not add auto-climate, and does require the purchase of a Seat Control Module or Seat Climate Module (SCME, sold separately). It allows the original XLT heated seats to be used with the upgraded radio/climate bezel. Thanks!

I have been able to design and test a plug-and-play harness with an OEM seat module (along with some Forscan programming) to enable the heated seats originally installed in an XLT when you install an Autoclimate control bezel. I can confirm it works with 2017 XLT so I believe it will work no problem on a 2015-2016 XLT. I am doing some research to see if it would be compatible with 2018-2020 at the moment but I have not been able to make a determination on that yet. I am putting the final finishing touches on the first (original) harness tonight and tomorrow night that is installed in my truck.
Others be fairly warned, we all listed to this months ago, some of us moved on to other solutions.
I'm sorry if I did post something and give false hope early on in the R&D process.

Was there someone else working on this? I only started looking into this in early June, I didn't even really know this was a thing until late may when I saw the bezel. I started digging into this June 8th and then I got busy with my real job and housework. I got back to it when I had a little time and when the weather began to call for heated seats.

but here was his PCB design maybe you can use it

he was saying by using that he thought he could do both seats with one box and have it cost less than 50$
I'm not sure that i believed the price but i would have easily payed twice that for it to work
a lot of us volunteered to help him but he never got with anyone except a message saying that he would reach out when he needed testers
yes it was another member named @Fiasco17 he kind of faded away, after getting all of our hopes up

I see. I apologize for anyone else getting your hopes up and letting you down. I am trying really hard to prevent that. I have a couple people I am working with and have their harnesses in progress (ordered all the parts/pigtails). I will admit when I started looking at the OEM pigtails for my harness I hit a little wall because it is expensive but I finally decided to just buy the pigtails and try it out. If anyone wants photo proof that the harness exists please refer to my build thread. Thanks!
Edit: Oh, the signature came back when I posted from my computer instead of my phone.
