Basic injector/solenoid control wiring of the SMT6. This allows batch fire of 1 to 6 high impedance injectors (can run low imp inj but the total output is current limited to 7 amps, yes it is possible to make a fly back board to handle greater loads) If NOX INJECT software option is turned ON (global settings, system config) it pulses wire 21 at 38Hz allowing connection of relays to control solenoids for NOS or alternate fuels. This can also be used for boost modulator solenoids.
