got this from another forum:
BOSCH -------------------> Honda
BLACK (Signal) ---------> WHT D14 o2 Sensor Signal
WHITE (+) ----------------> YEL/BLK A25 or B1 (On w/Ignition)
WHITE (-) ----------------> ORN/BLK A6 o2 Heating control
GREY (- for Signal)-----> GRN/WHT D22 (Sensor Ground- any GRN/WHT will do)

In a nutshell.. The signal wire is strait forward and Yellow/Black wires are power, Green/White and Green/Blue are grounds for all the sensors. The extra (optional) Grey wire is just a ground for the o2 signal - a little better then a 3 wire setup i guess?
