The 1KZ-TE uses an electronic distributor-type injection pump (Denso) – no high-pressure injector drivers in ECU. The pump has a spill valve (RSC) and timing valve (TCV) .
The Engine Control Unit (ECU) maps electrical connection points for sensors and actuators. Depending on the model year (Early vs. Late), the pin configuration may vary. : +B, +BF : Battery power supply. IGSW : Ignition switch signal to activate the ECU. BATT : Continuous battery power for memory. Sensor Inputs : THW / THA : Water and Air temperature sensor signals. PIM : Intake manifold pressure (Boost) sensor. NE+ / NE- : Engine revolution (Crankshaft Position) sensor. TDC+ : Top Dead Center signal for timing. Control Outputs : 1kz ecu pinout

Found mostly on Automatic models.
(Crank Position) signals allow the ECU to calculate the exact moment to inject fuel. Correction Resistors IGSW : Ignition switch signal to activate the ECU
