If you open the wiring box on the fire wall there is a threaded stud
with red wires attached with a nut. One of the red wires goes over to
the fuel injection and powers everything but the coil and ignition
module. Also in that box is a single connector with black wire. That is
the power for the coil and ignition module as well as the small
pick/hold current for the 2 relays nearby. You could measure the current
on each of those 2 wires.
