ok so as we all know, you must convert to 4 wire o2 when converting to obd-1

heres my situation, i have 4 wires from the new jumper harness that go to the new 4 wire plug. they are as follows: blue(o2 heater controll), white(o2 sensor signal), red(power), black(ground)

those are the wires from the new jumper harness^^^

here are the wires on the new 4 wire o2 plug: orange/black, yellow/black, white(thick), green/white.



which wires from the jumper harness go to the wires on the 4 wire o2 sensor plug?? ANY HELP will be appreciated.

 

What brand is your O2 sensor?

 

bosch. but the plug is off of a 94 civic coupe(harness side)

 

It really doesn't matter what the plug wire colors are. Just make sure you wire so that the jumper wires reach the correct wires on the O2 sensor.

All Bosch 4-wire sensors have a black wire for the signal, a gray wire for ground and 2 white wires for the heater.
There is no polarity for the heater so it does not make a difference if you mix up the two white wires - heater will work the same wither way.

 

?

can you post up a picture of what you mean its kind of hard for me to paint a picture visually in my mind

 

blue red black and white are what im supposed to be using???
