The rear wiper wiring actually comes out of the hatch underneath the hinge. The hinge gasket on the hatch side has a channel molded in for the wiring to go thru. It comes out from under the hinge, then makes an "S" bend to allow flexing, then goes thru a grommet/hole in the body. Eagles without a rear wiper sometimes went out with the "non-channeled" left hinge gasket also on the right side; in which case you'll have an issue running the wiring as it should be. I might have a used correct gasket somewhere, but would probably take me a year to find it for a pic. Take a look at the wiring pics I just took of mine - hope they're legible.
