Just did the retrofit to my drivers seat on the weekend, and I can confirm that 61 12 9 131 729 is the correct seat bottom harness for those with power + memory + sport seats. Everything is simple plug and play, but getting the plastic trim off of the side of the seat bottom for the switch is a real b!tch!
Big thanks to SLeagle328 and Tomppa_AC for their DIYs! The addition of the lumbar support is much improved over the stock seat.
