Rick,
We are doing the same thing as you are. The inertia switch runs a relay
that shuts off everything electrical.
Costs about $20 at Ford (and others I guess) and the relays are about $5
each. I use one inertia switch and two relays. One relay for fuel pumps and
one for ignition systems.
It is proven to be effective on my liner...........
