I love the BMW seats I installed a couple years ago, but have always wanted to get the seat heaters working, so finally set out on that.
I had a sense of which wires coming out of the control module were for the seat heaters from some past research:
Here are each of those plugs, one for the back and one for the seat:
I ignored the grey wire, I assumed it sent a thermostat signal back to the module (original seats had 3 different settings), and just wired together the brown and greens (brown is typically ground in BMWs):
They heat up! warmest I clocked after sitting on the bench for 30min was 119°
I picked up some expensive OEM switches off ebay, but wanted them to fit in OEM slots. And, since I was only going to have one setting, I wanted switches to match (which isn't that common). All my center console switches are now filled...curious what extras when in these from the factory.
While I had things torn apart I took the opportunity to clean up and paint this rusty center console support:
and put 3-in-1 sound deadener on the floor:
Toasty bums!
