Wiring harness extension for HPFP retrofit on Gen1 B58 engines

The CTS Turbo wiring harness extension solves a critical challenge when retrofitting upgraded high-pressure fuel pumps to first-generation B58 engines. This purpose-built harness provides the necessary length and correct connector configuration to integrate later-specification HPFP units into earlier B58 platforms. Essential for professional tuners working with A90/A91 Supra and F22-chassis BMW 230i and M240i applications, it eliminates wiring modifications and ensures proper signal communication between the ECU and upgraded pump. A must-have component for workshops performing serious fuel system upgrades on these turbocharged straight-six platforms.
