Re: bosch o2 sensor?
It should come with a set of instructions that tells you what wires go to where. :P Make a list of the honda wire colors for the o2 (I'm too lazy to search through my manuals) and i can tell you what wires go to what. On the bosch sensor...black wire is ground, 2 white wires are for 12volts and heater control (these 2 wires can be switched around...) and grey is for o2 signal.

sorry i dont know what i did with the instructions. ive heard the grey is optional and the green is ground though. and the two white wiqes aqe heaters. problen is i dont know what wirer are what on the stock sensor. they arent a match. also instead of using the supplied connector i sauldered every thing but now i hear that is wrong because the wire is aluminum and the saulder could melt with the heat fr6m the exhaust.
