On the 92 Accord (probably similar to Legend) the VSS is boat-shaped (square on one end and pointy on the other. It has a three wire connector and is mounted on the top of the transmission directly under the thermostat housing. To change it you unplug the wire connector and remove two 12mm bolts. Take care not to lose the white plastic drive pin. Typically these are on the top of the tranny so they don't get as wet. The three wires are +12, gnd, output (+5V pulse).
