just be careful with the ampere meter, most of them are limited to max. 10A unfused often less. If the fuse of the heater is for example a 8A type, the heater must draw more than 8A to melt the fuse. As the fuses in cars are not fast types, it could happen that your heater draws more than, for example 10A, you fry the ampere meter before the fuse melts. So check that the fuse melts before the ampere meter gets fried.

Check that the fuse melts long before the ampere meter gets fried.
