Adapter Harnesses

Adapter harnesses are used to convert the wiring loom of the vehicle from one generation to another - usually from OBD2 (1996 and up vehicles) to OBDI (1992 to 1995 vehicles).  Note that these adapters are for off road use only within the USA.

These models and years are a rough guide only - often the wiring loom in the vehicle has been altered from the original.  1998 and 1999 Civics and Integras may have either of the two adapter types. 

Please physically verify the type of wiring harness in the vehicle before ordering.
