  • BLOX Racing ECU Jumper Harnesses make ECU wiring a snap and totally pain free.

    BLOX Racing harnesses are made using a specially made, silicone fiber-reinforced wire providing better heat protection and resistance to oil than our competitors. Each connector is pinned to ensure that factory sensors are available to reuse. The secondary pigtail provides the necessary starting point to wire in a 4-wire oxygen sensor, VTEC solenoid and pressure switches and knock sensor. BLOX Racing has also included provisions for set-ups choosing to reuse the factory IAB solenoid.

    Using an OBD1 ECU provides greater tuning capabilities for high horsepower engine builds.

    For this particular application, this harness will connect an OBD1 harness to an OBD0 chassis.
