Where does a 1984 Lincoln Town car inertia switch get it power?

The inertia switch in a 1984 Lincoln Town Car gets its power from the battery, typically through a fused circuit in the main power distribution system. It's in the power path to the fuel pump relay, so power flows *through* the switch to the fuel pump. The switch itself doesn't have a separate power source; it's simply a normally closed switch that breaks the circuit when it's triggered.
