The breakthrough came when Alex discovered a small, dedicated community of Suzuki enthusiasts who shared his passion for engine tuning. They provided him with valuable insights, shared their own documentation, and offered guidance when he encountered roadblocks. | Connector | Pins | Color | Function

Essential for cold starts and radiator fan control (often Pin C5). Power & Ground:

The Crank and Cam sensor signals are incredibly sensitive to electrical "noise." If you are extending these wires for a swap, use to prevent the engine from misfiring or cutting out at high RPMs. The "Check Engine" Light Trick Essential for cold starts and radiator fan control
