Well, I am not %100 sure if the '95 had the option for headlight washers, but if it does, it will have some little spray nozzels sticking out of the front bumper about 3 inches in front of the headlights.... two nozzels per side.
I believe it will have the twilight sentinel, but I don't ever use it in my '93 SSEi, so I can't honestly tell you for sure if the headlights come on automatically at night..... I think that they might if you have the twilight sentinel on.
as far as an owners manual goes, post a topic in the wanted section. We have many members here that have that stuff just laying around, and also many members frequent the junkyards, so they might also be able to pick one up for you.
