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?

 

Did you wire up some resistors to act like a heater wire for the ecu?

 

its cool now i just reconnected the stock o2 to the stock connector and ziptied it to the firewall...works fine now...thanks
