So wait, this is some sort of latching relay setup thingy? So is the
[starter,fuel pump,whatever] disabled when the relay is latched, or when
the relay drops out? On the one hand, depending on a latched relay to get
and/or continue moving seems like a violation of KISS, and on the other
hand, if the latched relay provided the cutout one could "unlatch" the
system just by cutting the power momentarily. Which way did they use? (I
use a fuel pump cutoff switch hidden behind my fire extinguisher myself;
originally put it there so I could cut off fuel while grabbing the halon
bottle in case of an engine fire, but it's a handy vehicle theft
complicator too)
