Many sensor ground wires (often color-coded Black/White or Black/Red) are wired back to the ECU to prevent voltage offsets from causing inaccurate readings.

Suzuki uses a standardized base color and stripe system for its wiring looms: = Black W = White R = Red Y = Yellow G = Green L = Blue Br = Brown Lg = Light Green P = Pink V = Violet

The ECU triggers the Main Relay to power itself and the sensors. If the ECU doesn't "see" ignition power, it won't ground the relay. ⚠️ Important Technical Notes VVT vs. Non-VVT: This product is a great resource that will

Tip: Always match your ECU part number (e.g., 33920-XXXXX) to the vehicle chassis code (JA22W, JB23W, DA62T, etc.) to guarantee wire-to-pin accuracy. 2. High-Quality ECU Pinout Master Reference

Switch to high-density, multi-pin block connectors (often 60-pin or 84-pin configurations). Core Wiring Architecture
