I may be a bit late with this post from your earlier post, but I upgraded base cloth seats to leather seats. I wanted the power seat adjustment, was not interested in the heated seats- don't drive in winter. While the connectors were the same, the passenger seat sensor of the leather seat was not being read by the seat belt/safety system. The solution was to take all of the safety components (the seat bladder that sensed when someone was seated) from the original cloth seat and build onto the leather seat so the CF believed that it was reading the OEM cloth seat. The install got pricey because of this dissection. I'm told that the seat connectors from year to year and model to model vary. I read some posts that mentioned "plug and play" and others that had to adapt connectors, not to mention what my CF had to endure. I'm thrilled to have the power seat adjustments for long rides. Hope this info is helpful for others.
