Again, correct sir. I pulled the center console harness from the same laramie for testing purposes and installed it, along with wireless charging and the cd player, in my rebel. All of it bolted/snapped right in place. The main harness connection matched up pin for pin to the new laramie console harness when reviewing the wires. After activating in alphaobd everything but the rear heat switches are functional. I'm under the impression the rear is exactly like the front in that if the canbus can't communicate with the module then the switches don't work even if they're physically there. I'll be testing that as I move forward.
Regarding the front, I'll snap some pictures of the differences between heat vs ventilated when I get back in the garage. Basically you could install the blowers on the seat but would need to modify the foam and get a new harness or build your own. Either option works just fine, I just happened to find a couple full seat seats to play with for reasonable prices. Having never seen anyone do the full swap I didn't want to be without needed parts.
