Question about 1998 Toyota 4Runner
Appx 6 " from the sensor, there is a 2-part plug connecting it to the wiring harness...somehow, the wires were pulled out of the plug, & i do not know the correct way to reattach them, since the color sceme differ differs..
from the sensor itself, the wires are a)blue, b)white, c)black, and d)black..
to the harness, the wires are A)red/white, B)white/blue, C)red, & D)brown...
i do not want to burn out my car's computer trying to find which wires
go where, & the harness display i show does not show this plug, at all..
i cannot take my smog test until this connection is made, so this info would be greatly appreciated at this time..
ie. a>B b>A c>D & d>C thank you bruce
please help me, only, if you know for certain...

go to any auto parts store and ask for a 12 volt test light, it has a bulb inside and a pointed end like an ice pick, u attach one end to a good ground and then probe wires for power, when u have a hot wire with 12 volts the light in the handle will shine on. They cost about $6.00 at Kragen I think.

the best thing to do is get a 12 volt lite tester the one with the pointie end. cut your harness turn on left turn signel. with tester lite grounded tuch the ends of the cut wire from truck strip a small piece of wire covering and attach to your trailor harness when left signal works on the trailor do the right blinker the same way as for running lites turn on your park lites and see witch two wires are lit connect to trailor making shure lites are dim last wire are for brake lites now you well know where to connect to new harness good luck cj

Removal of the oxygen sensor is easier when the engine
temperature is above 48CC
' Handle the oxygen sensors carefully in order to prevent
damage to the component.
Keep the electrical connector and the louvered end free of
contaminants. Do not use
cleaning solvents on the sensor. Do not drop or mishandle
Numbers in ten in parenthesis correspond to numbered
components in image.
1. Raise and support the vehicle.
2. Disconnect the sensor harness connector.
3. Remove the oxygen sensor.

Important: A special anti-seize compound is used on the
oxygen sensot threads. The new
service sensors should have the compound already applied to
the threads. Coat the
threads of a reused sensor with anti-seize compound P.N
5613695 or the equivalent.
1. Install the oxygen sensor.

Important: Make sure that all of the harness retaining clips
are intact. The harness
must not contact any of the hot exhaust components. The HO2S
pigtail has white
tape at the intervals, indicating the proper location of
each retaining clip. When
connecting the sensor pigtail to the harness, ensure that
the connector seal is
crushed uniformly all the way around between the connectors.
2. Connect the sensor harness connector.
3. Lower the vehicle
