The cooling fan works when jumped but does not when harness is plugged back in I have a new temperature sending unit. But I am trying to locate the cooling fan relay

I would check the alt-fan fuse in the fuse panel on the left side of the engine compartment. The cooling fan relay is on the left side of the engine compartment near the battery. There is also a fusible link at the left front of the dash at he battery junction block. Check out the images (below). Please let us know what happens.
