    The wire runs up into the center console base. But you don't need to go that far. Just above there should be a stay that holds the plug suspended above it's o2. I'd take a pic for ya, but my 2000 ex is no longer OBD2.

    Not the secondary o2.

    It comes thru a grommet into the cabin in front of the shifter in the bottom of the center console, to be more specific. But the clip is on the underside of the car.

    The secondary o2? How in god's name could it be by the distributor?? The secondary o2 is located in the cat. Are you referencing a 2000? Interesting..., but I know my car.

    That's completely weird. I've finished my wire tuck not too long ago tho. Deffinatly comes thru a grommet in the floor. I couldn't imagine that o2 running all the way to a disconnect clip by the dizzy. It would be rediculous to replace that 4-5 foot piece of section when replacing that o2. Idk man. I've got my haynes here too, 96-00. lol

    To Demack, noooooooooooooooooooooooo. I was trying to be clear it's on a stay (which is a mount for the clip to be held) above that o2 which is above the cat in that cavity.

    If you happen to have a Haynes manual, #42025, picture 12.7 shows the location of the plug. It's in the upper left of the picture.
