How do you replace the driver's side taillight assembly on a 1995 Nissan Altima?

First go into the trunk and pull back the molded trim piece behind the tail light, (it should not be connected any where just pull on it and it will come free. Now you will see 4 bolts with nuts on them and that is what holds your tail light in place remove those 4 nuts and gently push the light out from behind then unplug it when you see which plugs need disconnected put you other light in place (make sure the rubber gasket is around the light to prevent water from shorting out the unit)plug it in and bolt it down, replace the trim piece and your done... good luck
