NEED OWNERS MANUAL
I try eBay first for owners and repair manuals.
According to Wikipedia, the Nissan 200SX was sold from 1995- 1998...I don't any evidence that anything beyond that was manufactured (unless they did so overseas?) - - - - http://en.wikipedia.org/wiki/Nissan_200SX
You can try http://infoservicemanuals.com because there i've find the repair manual for my car.
