FWIW you can use the one with the heated / cooled seats. You need FDRS to PMI it to your truck if you don't have cooled seats. The cooled seats button won't work, but FDRS will program the heat properly. The heat-only seats are powered from the HVAC control module. The heated / cooled seats are powered via the DSM under the driver's seat and requires a few more bit flips as well as dedicated wiring between the seats and an additional power cable ran to the drivers seat.came across this one another forum. anyone seen before and know part number?
I PMI'd the HSW / platinum unit from a 21 MY and the heat worked with XLT seats. After I swapped seats out it the heat showed working but the seats are wired to get heat from the DSM. After the install I flipped several forscan bits and the heated wheel + heated / cooled seats work as they should.
