Because wire colors change between a 1994 Hilux Surf KZN130 and a 2002 Land Cruiser Prado KZN165, you must always verify pin positions by function rather than color. 1. Power Supply and Ground Circuit Controls the fuel quantity injected into the cylinders
To ensure a smooth wiring process, always use high-quality automotive-grade wire, avoid wire nuts or T-taps, and heat-shrink all your soldered joints to protect against heat and vibration.
The NE sensor (pump speed) and G sensor (pump timing) are crucial. These must be shielded wires to prevent interference. PIM (Pressure Sensor): Measures boost pressure.
