install plx wideband/narrow band
 

I purchased a narrowband replacement that also has a wideband output. plx 400m

The question I have is how do I replace the stock o2 sensor, there are 4 wires, under the car: 2 grey, white and black.

The replacement o2 sensor has 1 grey wire for narrowband. 12v and ground.

My question is what wire/wires do I need to splice into the grey new o2 sensor to have everything working correctly? Also do I splice the wires under the car at the old o2 sensor, or do I run the new 02 sensor wires to the ECU (if so which wire am I splicing into the wire, or am I cutting in half and connecting to the ecu input)?

Has anyone had success with swapping this o2 sensor, or should I just get a bung welded on and keep the stock one alone?

thanks in advance.

Get a bung and weld it on. Don't mess with the stock o2 sen. You will get a CEL.

Check out this, i have wired my PLX the same way and it works perfect!

Sorry for bring this back from the dead, but I need to know which pin in C101/404 it needs to be. Is any BLK/YEL wire okay to tap for +ve?
