ls o2 sensor

[injen78]

well the previous owner cut the o2 clip off the engine harness and cut the clip off the actual o2 so hes staring from scratch

[toddmsc]

my o2 is a UNIVERSAL 4 wire

wire colors on o2 are:
1 black
1 gray
2 whites

and the harness is:
green w/ white stripe
white
yellow with a black stripe
orange w/ black stripe

i just need to know how to hardwire them together because there is no plugs

thanks doitpropa but i need o2 to harness not to ecu i just dont have the plugs so i cant plug them together

all u need to do is find wut colors ur o2 sensor are like wut the black and the gray is as in signal or signal ground no wut i mean if u had them they shoulda came when u bought it or u could always try it nd if it don't work switch the wires till it does

Well i messed with the wires and it is finally hooked up. However, A/F gauge is all over the place sometime its rich. Others lean and sometimes it even goes off the gauge and then nothing shows up.

CEL still on

[doitpropa]

did it die after a few mins ? if so switch the 2 same color wires

[toddmsc]

no the car never died. The cel is still on and the A/F gauge is EVERWHERE
