The black wires are the heater wires, the white wire is the signal wire and the green is the ground wire.

At the bottom of the PDF is a wiring guide for bosch sensors, Competitors, and OE harnesses. The guide is from bosch, it should work well. You will notice the GEO has a different stock harness than is typical.
get the right oxygen sensor
Saab used heated oxygen sensors on this year car. There is a heated Bosch Universal sensor that will fit; you cut the plug off your old one and wire it to the new sensor. If you mean "how can I replace the sensor on my car with the $15 version that doesn't have a heater on it?"...unless you really like check-engine lights you can't. The car's computer will notice the sensor isn't talking to the heater circuit, assume the sensor's burned out, and start throwing codes all over the place.
where is the iat sensor on my Mazda 6 located and does anyone have a pic to compare
need to know what wire go were for a 94 Mazda protege MAF sensor
bosch 15716 and bosch 15718 are the same exact sensor, the difference is the length of the wiring the 15718 has a longer wire. Both sensors would go before the catalytic converter. 15717 goes after.
To replace a universal one-wire oxygen sensor with your 1997 Ford Aspire's four-wire setup, first locate the existing sensor and disconnect it from the wiring harness. The four wires typically include two for the heater (usually a pair of the same color), one for the signal (usually a gray or black wire), and one for the ground (often a white wire). Connect the signal wire from the universal sensor to the corresponding signal wire on your vehicle, and connect the heater wires to a power source and ground as per the universal sensor's instructions. Finally, ensure all connections are secure, and reassemble everything.
Near the intake manifold, a small plug and wire sticks out on the pipe.
The sensor is threaded into the head to the left of the thermostat housing and has a single wire connector on it. Thanks Malcolm
look where your oil filter spins on it will be next to it it screws in and has a wire pluged on it.
you have 2 , look at your exhaust manifold there should be something sticking out with wire or wire going to a plug, there is another on your catalytic converter.
