3. Step-by-Step Wiring for an Engine Swap (Standalone Configuration)
Wiring a 1KZ-TE doesn't have to be a nightmare if you tackle it one plug at a time. Always verify your specific ECU part number, as there are slight variations between the Hilux (KZN165) and the Prado (KZJ95) pinouts, particularly regarding the air conditioning and automatic transmission shift points. 1kz ecu pinout

The ECU has :
The acts as the brain for the 1KZ-TE, managing fuel injection timing via the Electronic Spill Valve (SPV) and monitoring engine vitals through various sensors. Because the 1KZ-TE was produced over several years (most notably from 1993 to the early 2000s), there are distinct variations between "Early Model" (3-pole/plug) and "Late Model" (4-pole/plug) ECU configurations.
