Decide Which you want to keep (Body would be best as the bumper ones get mullered)
In the body behind the light you'll find the connectors for the lighting units, one for fogs, one for the clusters on each side. Then its a matter of connecting the set you want. You'll need to break into the harness and add another connector for both and the wiring down there is usually in a pretty sorry way.
If you are keeping bumper lights, go get the fogs of another vit, most have body mounted fogs. You can try finding bumper fogs but dont fancy your chances. Blank off/paint the clusters and put external fogs on,. You should be able to pick up the wiring in the body cavity behind the light clusters.
