Can someone please confirm for me?? 02 signal input pin positions on the ecu
I am going to install a dual output sim Id prefer not to install it in the engine compartment and I intend on installing it near the ECU.
I Intend on intercepting within the ecu harness pin 55 for o2 sensor 2 bank2 and pin 74 o2 sensor 2 bank 1 Both are labelled "L" I presume for lavander??
Is my information correct? Ive had a hell of a time trying to figure this out.
It also makes me wonder why no one does it this way? Is there some reason?
If not maybe ill take pics and try to do a decent write up of my install.
dunno if its in my sig Have to update if not but 2004 Maxima 6 spd.. Thanks All!!!

Correct, pins 74 and 55 are B1S2 and B2S2 signal (respectively).
Right at the ECU should be fine, AFAIK. I can't think of any reason not to.

Hi pmohr,
I own a cefiro/maxima/teana j31 too. I'm located in Singapore. So it's known as cefiro here. It's a 2007 model.
The engine is qr20de. Do you have the ecu pin code for this?
