Whoops, sorry. That was a picture I used for something else, and I didn't realize it still had the circle in it from the little one on photobucket

Jeez, you wouldn't believe how hard it is to find a decent picture...in fact, I can't, and don't have my car with me right now, or I'd run out and take one. All the pictures I have of it face the engine compartment the other way for some reason, and apparently so do everyone else's.

I drew a red circle in this one around the area where it SHOULD be.

Right in front of the windshield washer fluid fill cap, there's a little black thing like you saw on the FCP site with a wire going to it - it should be one of very few wires in that area that comes up and connects to something other than the headlight.

Mine is also a 98 model, and it IS there.

If your car is throwing codes for it, I suggest unplugging it and cleaning the connector with rubbing alcohol. I did this for mine (and also accidentally dropped an entire pan of wrenches on it trying to fix something else), and the code that I was getting every 3 days or so hasn't appeared in more than a year.
