This NSP wiring page is where you assign outputs for the sequential twin turbo system. You'll need it when setting up an RX-7 FD or Supra JZA80 style system for the first time, or after moving solenoids to different pins.
Four valves each need an output: the Pre-Control Valve, Exhaust Valve, Charge Relief Valve and Charge Valve. A DPO (Digital Pulsed Output) is the usual choice, but any free output will work. The wastegate is handled separately through boost control.
What to check: each output matches the pin the solenoid is actually wired to, the solenoids have switched 12V feeds, and each one clicks when you test its output. Then set Secondary On RPM and Pre-Control Duty Cycle.
