There is a black wire from the key switch that runs back to the engine
compartment and stops first at the coil. From there it runs to the relay
box. It triggers the ECU power relay, (next to the FP relay). The ECU
controls the FP relay.

Measure the voltage at the coil stud where the 2 black wires attach. It
should have 12 volts whenever the key is on.
