ramsayh--question for you regarding 2005 AFR signal

ramsayh--question for you regarding 2005 AFR signal

ramsayh--question for you regarding 2005 AFR signal

(OP)
I have been searching for some information on a 2005 Altima's AFR wiring. Precat--only seems to be one.
4cyl.

There are 5 wires as follows:
red
black
grey
white
yellow

I need to know which wire is the signal FROM the AFR to the ECU.

I believe the grey and white are the heater wires, but not sure.

Alldata and my local nissan dealer show very different wiring colors, so they are no help.
Any help would be greatly appreciated.
