When working with a 2NZ-FE ECU pinout PDF 186 portable, keep the following tips in mind:
Low-side switched ground outputs that trigger fuel delivery sequentially for cylinders 1 through 4.

Splicing the main power feeds (+B and +B1) into thin, existing under-dash wiring can cause micro-voltage drops when the cooling fans kick on. Ensure these pins are fed via a dedicated 15A or 20A fused relay directly from the battery distribution box.
Is it a or an electronic drive-by-wire throttle body?
Tachometer output signal for your dashboard RPM gauge. : Labeled A, B, C, and D, these
Detailed voltage specifications for 1999–2004 Toyota Echo models with 1.3L engines.
Fuel injector drive signals. The ECU switches the ground side of the circuit to pulse each injector.
The 186-pin system uses a highly sensitive ETCS-i circuit. If the VTA and VPA dual-voltage pathways do not perfectly mirror each other within the factory-specified millivolt tolerances, the ECU will cut power to the throttle motor (pins M+/M-), illuminate the check engine light, and lock the engine into a 1500 RPM safety idle.
