Hello
Im from sweden and the winters here can be cold so i'd like to install a parkingheater in my -98 STS. Has anyone done this? I dont know how to connect the heater to the ventilation fan.. Any ideas?
Help is much appreciated.

The only "heater" listed for the Seville Northstar is a pair of 110 VAC Calrod elements which bolt to either side of the engine block in order to maintain coolant temperature at about 60-70 degrees F.

Several of our members live in colder climates than I, so someone else will offer advice later in the (U.S.) day.
