just bought a 1995 e320 and found passenger side backup light doesn't go on. when I openned tail light assembly I found bulb missing, but more so the contact and wire lead for that bulb position are missing too. there are total of 6 leads coming from the wire clip. compared it to drivers side tail light and found that one has 7 leads. I'm beginning to think P.O. replaced the wiring and right tail light assembly with same from a different year, perhaps due to collision repair? the dash "bulb" light goes on soon as I shift to reverse, so the car senses something should be there.
any helpful insight appreciated.
