Replacing O2 Sensor What color are the original: Wires
I need to know the color for the wire from the O2 sensor to the computer, the color from power source to the O2 sensor, the color of the power for O2 heater and the color of the ground for the O2 heater.
2004 Buick LeSabre
I have a Bosch replacement, not original, so the colors do not match. and need to splice wires to the original plug.
ok 2004 lesabre I can access the technical info tomorrow at the shop I will give the info and instructionsok 2004 lesabre I can access the technical info tomorrow at the shop I will give the info and instructions

The 2010 Dodge Caliber O2 sensor wiring has four wires: two white, one gray, and one black. The wires are typically color-coded, so you should be able to match them up with the wires on the replacement O2 sensor.
Here is how the wires are typically connected:
White wire: Sensor signal wire
White wire with black stripe: Sensor signal ground wire
Gray wire: Heater power supply
Black wire: Heater ground
You can use a multimeter to confirm the correct wires if you're unsure.
If you purchased a good quality sensor (Denso) that is for your vehicle, it should have a new connector plug already on it. The colors shouldn't matter as long as the plug is the same as your original one. If you purchased one without a connector (they are cheap sensors) then good luck. If this is the case, I would just match the wires by location on the connector pins & you should be good. Myself I would return it for one with a connector already on it.
Right do you mean the wires to the O2 sensor from the loom or the wires from the plug to the sensor ,So i will explain what i know here and thats all i can do for you.On our europeon motors their is a 4 and 3 wire O2 sensor type,now on the sensor side of the plug their will be two wires the same colour normally white or gray ,these two wires are the heater circuit so should show a resistance with a meter ,now the coresponding two wires in the loom plug should read 12v with the plug disconnected ignition on .Now the other two wires are for the readings so push a pin through each cable and then with engine running plug connected you should read 0-point something which varies with engine speed somewhere between point 7 to point 2 varying with speed .if it stays around the point 4 mark then replace as its not working correctly ,you should be able to read the voltages with a code reader though
Locate the wires running off
from the O2 sensor. There should be two. The black wire is the ground
wire. The other wire, which may vary in color, supplies power to the
sensor.
2
Connect the power lead to the corresponding connector on the chassis's wiring harness.
3
Connect the black, or ground, lead to the corresponding connector on the factory wiring harness.

wires, "how do i wire it" are simply explained. all universal 3 wire o2
sensors will have 2 wires one color, the other wire a different color.
the 2 that are the same color are ground and power for the heater and it
doens't matter which one is which. so ground to the motor, power from
the gray wire on the fuel pump, or anywhere you want to pull 12 volts
while the car is running. i have a dedicated fan relay that doesn't use
the ecm and runs off the key, so thats where i went. the different color
wire goes to the stock sensor wire, it's the signal.
First what do you mean by a universal o2 sensor? You must make sure that you have the right o2 sensor, most newer vehicles have four o2 sensors 2 upstream and 2 downstream, upstream and downstream are meant to show where the sensors are in relation to the catalatic converter,some o2 sensors have 1 wire or up to 4 wires most with four wires are heated o2 sensors so you need to be sure you ve gotten the right o2 sensor for you vehicle as well as the right replacement for the proper location! My experience is that most after market o2 sensors have the same colored wires as the vehicle. Also most o2 sensors have electrical plugs? If you need help finding the right o2 sensor for your vehicle then please dont be affraid to ask!
I Have Purple , 2 Brown, 1 light- off white, maybe tan.
Thanks, That should Help, I appreciate the help.
