I did this on my aunts 96 Civic.


Bosch Side --------- Honda Side
Black (Signal Wire) = White
2 Whites (Heater) = 2 Blacks
Gray (Ground) = Green

If you have a obd1 car the colors might be different so just double check. This is how i found this information, by searching. Theres tons of threads on this.
