Still might as well test the trunk and glovebox light/switches by
turning them off "manually", at least. Easy enough to do.

As I recall, the WUR is on the "Jetronic" fuse. TT sw. should only be
active while cranking.
I think a typical Bosch relay coil draws about half an amp, but that's a
very fuzzy memory of them being about 24 ohms.
