This harness is designed 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.
Note: For USDM Spec ECU applications, installation will require a secondary 4-wire oxygen sensor .
