Does anyone know where to find OEM part(what is OEM?) I also need a sensor. I assume that buying from the popular auto part stores sell after market sensor-help.
usually there is only 1 way for the connectors to slide together if still unsure call your local parts store use a OEM part and not an after market sensor-Your OEM sensor should plug right into the old one. If you try to splice in an after market sensor you will have nothing but headaches and problems
I found some good reference info on this topic at: http://www.4crawler.com/4x4/O2SensorWireColors.html Accordingly the sensor wire colors for Toyota O2 sensors (from the sensor to the plug) would be as follows Blue = Sensor + White = Sensor - Black = Heater Black = Heater
This tells you which oxygen sensor is out, look at your vehicle diagram to see where this sensor is located.
For the 1993 Toyota Tercel, the O2 sensor has three different wire colors. These colors are: black, blue, and white.

best bet: look up the sensor on the internet and see if they have a diagram. Usually white is neutral or ground and black is hot.
The O2 sensor wire colors are as follows: Purple or Purple/White- sensor input to the pcm, or computer Tan or Tan/White- sensor return (common) to the pcm Pink or Brown- 12V ignition power to the O2 sensor preheater Black or Black/White- 12V common or ground return to chassis for O2 sensor preheater.
power is Black or Black and yellow starter signal wire is black and white see wiring diagram link below..
the black wires are for the heater circuit, the blue and white are the sensor wires. the universal sensor probably wont work though, its best to bite the bullet and get the correct one from toyota.
the throttle position sensor should be on the side or the bottom of the throttle body. it is a little black or silver piece with 2 screws on it
all colors are in black. If you mix all the colors together you will receive black.
This truck does not have it seperate. It is built into the mass air flow the wire colors are tan andtan/black
There's no universal color code for oxygen sensor wiring. Buy the right sensor, period. If you're buying a generic sensor for your car (possible, but there are still many different kinds) and need to splice the wires from the new sensor to the car, usually the black wire is the ground and the other wire is "hot." With three-wire sensors, try to find a wiring diagram online to match up the colors. It's risky using a voltmeter or test light to find the hot wire(s), because you could fry your computer.
