Gasbo

Looks like there's a brown one in there

Yes, factory fit memory both sides; just driver has additional massage function (which is totally useless BTW!). Got to the connector and managed to remove it , but cannot, for the life of me, work out how to expose the wires. What's the trick to this?

That's the one! Comes as part of the vented/leather seat option (in Aus).

Mine has got the heated / memory seat option. A quick look under the seat shows a whole heap of different connectors. Which one in particular are you after?
