Brake Pad Wear Warning Light

[Grant Lenahan]

That would have been useful to knwo earlier!

OK, its a fairly simple circuit. Current sensing loop.  Either a short to ground, or an open circuit will reduce current.

Either one of those conditions exists - even in your abbreviated (jumpered) circuit, or the sensing circuit is faulty.
