Aside from the big main connector and the red and black wires (power/ground). I have the problem understanding where the last two grey and white wires need to be tapped into.

The shady instructions say the white wire is for "narrow band" and the grey is for "wide band". or vice versa. Either way, where do they friggin go to??? Is that for data logging function only? I just want my m300 to display my A/F's i am not running datalogging or any piggy back stuff. Thanks to all that help me out, as i have everything all strewn upon my interior waiting to figure that out.

 

he narrow band out is to go to the ecu to function as a regular o2 sensor ..

the wide band out is for a datalogging software ..

if your running your stock o2 sensor then you should be good to go

 

so basically i dont even need to hook those 2 wires up to anything? I am running an OEM o2 sensor and thr PLX WBo2 as well. I just want the PLX to display accurate A/f's via wideband.

 

just as the other guy said, just leave em hangin, thats how mine are.

 

Yea, you don't need those unless you are replacing your OEM o2 with the wideband, then you would need to run a capacitor in line too.

 

do you need to run the resistor if the o2 heated curcuit disabled?

i want to just run this single sensor rather than two but the guyu i got the ecu from said ( i dont have a o2 in there now and its not throwing a code so..) he probably disabled the heated o2 curcuit so what to do now?

any help would be cool

sorry to jack the thread

 

i got my info i needed to hear...
