The system (including the lumbar bags) is the same as on the L322 Range Rover, if it makes finding the loom and switches easier/cheaper! It's where I got mine from when I fitted this to my E46 years agoNice idea for lumbar support. Also one of my pet peeves of the E85 seats. I've bought a set of OEM E46 lumbar supports and am in the process of installing them.
