If memory serves correctly you need a 4 wire O2 sensor before hooking up one
of the wires to your electrical air to fuel ratio guage.

What is there to know? Are you hooking up a wideband? If you were to buy say... "AN" AEM uego. It comes with the guage and the oxy sensor. You screw the sensor into the o2 bung in the exhaust. You power and ground the guage. You plug the connector side of the sensor into the back of the guage. Some calibration may be req'd.

AN
AN
AN

you must use "AN" instead of "A," pending on the leading letter of the following word.
