I have a obd2a-obd1 harness with p72(jdm) ecu.

I am using the wideband sensor in the place of the stock sensor.

I want to use the wideband all the time to keep an eye on things.

I can figure out the black and red wires, its those gosh darn white and grey wires I'm not quite understanding. Not to mention talk of a resistor and caps.

Where do I tap into for the white wire? What about the grey?

I think I will tap the grey into d14 is that correct?

Then I won't have to do anything with the white wire because I'm not datalogging correct?

Now on to the resistors so I won't throw a check engine light.

I will have to tap one end of the resistor into the A6 wire and the other end of the resistor will tap into what pinout? Is it A25?

I am just not sure.

Will I need to use capacitors at all in my setup?

Cliff notes:

Gray wire goes to d14

Red wire goes to anywhere with key on power, if you know an exact pinout it would save me time from finding one thx.

White wire: no where

Black wire:a23

How does this sound guys?

And yeah I know this topic has been covered but not for my exact car and motor so I just wanted to make sure.

 

Here's what I did (a long time ago):
