Pick a relay, solonoid or an inductor.  A 12V relay will be slightly more
acurate because the inductance changes as the armature moves
in/out/away/towards the coil.  I haven't looked at the circuit but note that
there must also be a diode hooked up with the band (cathode) towards the
12V+.  This is because as the transistor is turned off,  the magnetic field
produced by current flowing through the injector collapses and that field
moves through the core and the winding generating a opposite polarity pulse
much higher in voltage than 12 volts.  Don't grump about it.  It's the
physics that makes the ignition coil function.  8-)
