02 sensor wiring

i recently bought 1989 s-1- 4.3,the wire from the 02 sensor is unhooked,does anyone know where to connect this wire.one end is connected to 02 sensor and other end is just hanging.

Thank You,

Should be a single wire hanging near that connects to it. Usually there is a bracket on the transmission that holds this wire in place. Look around for it. Sure needs to be connected for best mileage.
