im installing my PLX wide band in my factory left front bung. i took out the narrow band what to i do with the factory connector? do i lust leave it disconnected or what? help me out. thanks

 

I use the PLX WB to also simulate narrow band for the PCM. I cut the connector off the old narrow band connector off and wired the narrow band simulation from the PLX into it and plugged it back into the factory connector there.

 

thanks for the reply. do you remember what wires you cut and connected to the wide band?

 

As I was typing the reply I knew that would be the next question No I don't. You basically want to feed back through the signal wire to the PCM. Just the one wire. I think you will also start throwing codes for heater performance to that sensor since the heater will be gone. Think I had to disable that code in the tune.

Here is a link that might help. It also touches upon the heater problem. Fix with resistors to fool the heater circuit or turn off the code as I did.
