My 98 3L OHV Taurus station wagon back up lights wont work. Checked fuse, ok. Removed tail gate inside panel to access back up lights, both bulbs good. Checked both bulb sockets for 12vdc power with ignition on & shift lever in reverse. No DC voltage present. Checked the wire continuity between both bulb sockets and there good. The socket wire to ground is also good. I even went further and applied 12vdc to the interconnecting back up wire on the tailgate and both lights work fine. I am unable to check continuity between the tailgate backup light wiring and the fuse panel without proper wiring diagram. Can anyone give me some help in troubleshooting this problem. More so in locating the different areas of the wiring such as backup switch location so I can isolate the problem. Thanks
