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.
