The lighter is an ideal location since it is meant to supply current to heating elements already! The only problem is that it isn't switched...

The 5-series and X3 must have a separate, fused source for the heated wheel that our 3-series doesn't have.

Any ideas?
Jackboot, I don't know if you have heated seats or not but the power source there is designed for a heater. I don't know if you can put two on the same source but if you don't have the heated seats then you should look into finding the instructions for putting the heated seat retrofit. It will tell you where the power source for the heated seats is.
