OBD1 to OBD2A Reverse ECU Conversion Harness by SpeedFactory The SpeedFactory Racing OBD1 to OBD2A Honda/Acura ECU Conversion Harness allows you to use any OBD2A Honda/Acura M/T ECU in a 92-95 Civic, 92-95 Acura Integra, 92-95 Honda Accord (4 Cylinder), 92-95 Honda Prelude, and 92-95 Honda Del Sol. This harness is perfect for utilizing JDM Spec ECUs that are often included with Japanese engine swaps. We designed our harnesses to be superior to other versions available on the market by using original equipment style ECU pin connections on all plugs, lengthening the harness leads to 7″ and by using durable automotive grade wire that exceeds OEM specifications. Installation is simple and no cutting or soldering is necessary (for JDM SPEC ECUs). Plug in one side of the harness to your OBD2A ECU and the other side into your factory OBD1 chassis harness. Please Note: For USDM Spec ECU applications, installation will require a secondary 4-wire oxygen sensor.
