I have been going crazy trying to find the NSS on my 98 E320. My Back-up lights(both sides) do not come on when I shift to revers. I checked the voltage at the light bulb sockets and the connection points and I get 13.6 volt but I get only .07 amp. Since the bulbs and the light assembly are good , My next point to check was NSS which sopposed to be on transmission by geer shift but I can't find it. Is it possible on this model the used a different design to activate the back-up lights?

Thanks
