I had the console apart yesterday so I compared all the connections on the console harness to what my Bighorn harness has pinned. I discovered at least two circuits that need to be pinned for the rear seat heated and vented seats. Circuit A207 is the Fused B+ for the switches in the center console. Circuit D403 is the LIN BUS CBC 3 connection used by the seat switches and the wireless charger. I plan to add the fused circuit from the 12-volt outlet on top of the radio bezel. The LIN BUS circuit is the same BCM connector C5/E pin 45 connection in the Mopar instructions for adding wireless charging. So this can also be connected fairly easily. The remaining and unknown connection is circuit M124. I believe this may be the backlighting circuit for the seat switches, but I have not found it in any connector as of yet. See attached
My notes are confusing to me now, a year later; But:
Pin 1 is not shown on the list I printed. List starts with Pin 2. But, for some reason I decided I needed it. It's a RD/BL and I "spliced to PK/YL in truck" .Probably should have connected it to a Power Distribution Connector? It does not appear to be "Lamp Driver" as your list shows (seems it's Fused Ignition). And, now, I'm wondering what's the difference amoung Pin 1-Lamp Driver, Pin 6-Panel Lamps Driver, and Pin 7-Reading Lamps Driver.
Pin 5, OR/DB was in the donor harness. and I added it to my truck Note says ":Heat Seat Switches X 2. " I didn't document where it originates.
Pin 8 is not on the list I printed; and I have no wire in that pin now.
