O2 sensor question

Hey Guys,
I'm swapping motors in my 89 XR7 due to a head gasket issue and thought I might as well put new O2 sensors on. I've got a couple of new sensors left over from when I was trying to get my 5.0 Bird to pass emissions test but when I check the # it appears they sold me some for a Ford truck, part # NTK 22500. I can't return them now because I lost the bill and I hate wasting stuff so any way to make them work, threads appear to be the same, 4 wires going into a connector. I'm not sure how many wires are original as I haven't checked them yet. Any ideas are appreciated.

Thanks Tom
 
Well I checked mine today, they are 3 wire so I don't think it will work.
Any opinions, probably just end up buying 2 more anyways.
Thanks Tom
