Been searching for awhile and can’t seem to find a definitive answer on this... I currently have standard comfort seats with heat/lumbar and memory and looking to swap those for a sports seats (not adaptive) with heated, but no memory. Other than losing the memory function will there be any issues? All I need is for the seat tilt and heating functions work.
Under my drivers seat I have the standard connector and an extra memory module and was planning to leave the memory module unplugged.
Many thanks in advance for any insights/experience...

Did a quick test: unplugging the memory module causes the seat to lose all power which is not encouraging but hopefully the circuit that causes in that behavior is on the seat side and not on the car side. Anyway, looking forward to hearing from others.

In the big yellow connector box under the seat, power enters on the 2 larger spade terminals on the left side - one is 12v power (larger red wire) and the other is Ground (larger brown wire). Worst case, make a little pigtail adapter from the connector on your wiring harness to the male spade connectors in the new seat ad you should have power seat functionality. I can't tell you if that will throw a code. This is how I wired the manual Adaptive seats I put into my 928 and in my office to have the power recline work.

Thank you..! I looked under mine and saw the red/brown thick wires going into the black memory module. Looks what’s needed is to connect those wires to the new seat along with the other connections like airbag, seatbelt sensor etc and I should _hopefully_ have a fully functional seat.

Newold_M, Just checking to see if you did this on your car. I've got the comfort with memory, heat in my '12 GTS. Wondering if any version of sport seat will plug into my car. How'd yours work out?

Hi Adams,

Thanks for the reminder as I've been meaning to update this thread. Yes, the swap as a success! What I had to do was to take apart both memory and primary seat connectors and move the positive (red) wire from the memory connector to the primary connector. There is already a ground wire (brown) on the main seat harness so no need to move anything else from the memory harness. Before you do any take apart be sure to disconnect the battery otherwise you'll end up making a trip to the parts store to get a new fuse

How to take apart the connectors:


red power line on left that needs to be moved:



and moved... No codes and everything works as expected and passenger side mirrow still dips when put in reverse. Let me know if you have any questions..
