Do you know if this same BCM programming would work for a 2020 custom retrofitting 2021 high country seats? I got seats and bought wiring harnesses/memory bypass harness for them but was told by the guy who makes the harnesses that even if I got the thermostat controls that I couldn’t get Heat/cool to work because nobody had figured out the BCM. beyond my understanding. To me if you get them power and get an on off button they should work but apparently not.
