I don't know what happens if it's detached. I DO know that the engine 
will die if it's shorted in the 68 "A" system. I know because it 
happened to me, on the way to work, blocking traffic....  8-p

I think I've seen different responses with different systems. It 
seems likely that Bosch made changes in the later systems to make the 
system more robust in the face of such failures. Sort of a "limp 
home" capability.
