That would be awesome man. I have the control module (DCSM) and all the TEDs. I have all the wiring diagrams as well as the operation overview. I could wire the TED directly but that would be unsafe. The control module is what regulates power to keep it in the safe zone
On the original truck, everything is connected. From the trucks ecu, bcm, radio, hvac interface, you name it. So replicating the original truck seems unrealistic
There are many components on each network, but not every component is required for the seat controls to communicate with the DCSM. Those 2 can work by themselves. And that's the only way you're going to get the TEDs regulated like you're imagining. You can go into the control panel module, extend the internal switch circuits out of the module, and onto some switches that look right on your dash. The modules can be hidden, and still do their jobs. But they have to be wired like original to work like original.
Or you can build your own regulation system. There's nothing inherently "unsafe" about the TEDs running full-blast - just maybe uncomfortable after a while. A simple thermostat can keep them at comfortable (& safe) temperatures.
I called the guy, and he just direct-wired the TEDs to 12V polarity-reversing switches on the dash. When the seat got uncomfortable, he turned the switch off.
That's is awesome news!! I have no problem with wiring it directly. I was under the impression that it needed power regulation to operate. Thank you very much for your help.

Longshot here on old thread but I am installing an aftermarket kit in my Tremor now. I am trying to determine if I can integrated the OEM TED units with the aftermarket control module and better yet control with the oem switches (mounted in the side of the seats...…….I have all the oem parts off of a junkyard seat I bought.
I've installed 2018 mcs in my xlt. Hours of studying and mapping out wires was the key. I had to run a harness from the passenger seat to driver and then multiple wires from each seat to bcm and such. I have the full function in each seat as well as the multicontour features. However I cannot figure out how to activate the heated/ac portion of them. All the blowers are there so I know its equipped.
I put these seats into my square body Suburban this month and tackled the wiring. I have the heated and cooled features working. I've attached a wiring diagram I drew up.
