warnNET_FAMILYOEM-4-J ↔ PROTEUS-White35-27OEM-4-J "VTCS vacuum switch" [digital_in] is wired to PROTEUS-White35-27 "Analog Volt 8" [analog_in]. Analog and digital on one net. A switch on an analog input works with a pull-up and a threshold; an analog sensor on a digital input loses its value.
infoNET_FAMILYOEM-2-E ↔ PROTEUS-Black35-6OEM-2-E "EGR valve" [low_side_out] is wired to PROTEUS-Black35-6 "Injector 6" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency.
infoNET_FAMILYOEM-2-F ↔ PROTEUS-Black35-7OEM-2-F "EGR valve" [low_side_out] is wired to PROTEUS-Black35-7 "Injector 7" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency.

Notes

Auto-mapped by auto_map() from the library pin data on 2026-10-04. Review every wire against both manuals before building. Not wired: - OEM-4 AG: Constant +12V: rusEFI Proteus has no battery-constant input; not needed - OEM-3 M: Alternator control: no free low_side/ls_hs/injector/hbridge on rusEFI Proteus - OEM-3 U: Charge lamp: no free low_side/ls_hs/injector/hbridge on rusEFI Proteus - OEM-4 D: VVT oil-control solenoid: no free low_side/ls_hs/injector/hbridge on rusEFI Proteus - OEM-3 O: Tachometer output: no free tacho/frequency_out/low_side/ls_hs on rusEFI Proteus - PROTEUS-Black23 18: Ignition switch in: not fed (the stock ECU has no ignition-sense pin); feed it from a switched-ignition source
