Wiring can be the most daunting part of a project, Blox simplifies the process with their ECU Jumper Harness. 

This harness allows an OBD-1 ECU to be used in an OBD-0 Civic/CRX or Integra chassis. An OBD-1 ECU offers the use of additional features and greater tuning protentional for high horsepower builds. Vehicle must be equipped with or converted to Multi-Point Fuel Injection (MPFI). 

Each connector is pinned to the factory harness to ensure factory inputs/outputs can be retained. An additional connector and pigtail are included, presenting provisions for a 4-wire heated oxygen sensor, VTEC, knock sensor, pressure switches, and IAB solenoid (if needed). 

Blox Harnesses are built to last with silicone-fiber reinforced wire that exceeds OEM specifications. They resist heat, abrasion, and fluids. 

The Jumper Harness can be used to re-pin wiring or add accessories without the need to modify the factory harness.
