They are different on the harness iirc they were brown, black and blue or somthing like that, I know ones brown for sure. Its a three pin connector like you said, on a stock harness, it will be half way between between the main part of the harness that sits on the engine and the part were all the branches join and go into the firewall.

They are brown, White, and blue on the harness. The black wire damesta is talking about is accually white. Its shielded wire so when you look at it it looks black, but at the end of the stock where you plug the o2 in, the wire colors are black, white, and green w\ red stripe. Well that's atleast the colors on my stock harness. hope this helps.
