You need 12 volt and ground plus the signal from the O2 (Lambda) sensor.
They usually have 3 wires. If 4 wires it's most likely a heated type but
that dont need to be connected. Whoever sell you the O2 sensor should be
able to provide some info how to hook up the wires. Most O2 sensors have
18 mm x 1.5 mm.
