I forgot the '97 still had the square fogs, in that case you WILL need the two connecting wires as well. The square style fogs lights used 893 bulbs, to the best of my knowledge the 99-01 round style used H1 bulbs. (err possibly H3)
Welcome to the forums by the way, I see you joined this month.
The 99-01 Explorer bumpers will not be a direct bolt on as they are plastic. You can see the difference in the link below.

As long as he pulls the entire assembly (entire front bumper; including the entire plastic piece, both chrome inserts and mount hardware attached to the bumper) off the '99-'01 donor explorer, I don't understand why it won't bolt up? :scratch:
I very well could be wrong, so I'd like to know..
I should have made myself more clear. You just can't pull the cover and bolt it on. I just wanted the OP to be aware of what all he needed.
It would be much easier & cheaper to pull the square factory lights and put a set of round lights on. That's what I did but I don't have pics.
I'm just the opposite. I hate the 99-01 cheap plastic look.
