There is a manual available for download in one of the stickeys in this section.
The MAP sensor is located on the throttle body. It has 3 wires going into it and connected via a round connector. It will be held onto the throttle body by 2 screws. Do not mistake this for the Throttle Position sensor as I believe they have the same wiring connectors. The throttle position sensor was located on the back of the throttle body, while the MAP sensor was on the top on my '97 GSR motor.
