hi i just installed the plx air/fuel monitor... the 300... iin my 4 door civic with b swap... ran power and ground, installed the sensor and wired the narrowband gray wire to d14... my check engine light keeps coming on does anyone know the color wire of d14 so i can make sure i got the right one..or has anyone had this happen before?

 

you are probably getting a code for the o2 heater. you will probably need to wire in the resistor to get rid of it unless you are using an EMS that can disable the heater

 

yeah, that seems to be the more common problem.. 'cheater' resistor may be needed for the heater wire..
