I am putting a 05 5.3 in my 55 chevy using a stripped down stock harness with a/c and evap removed. I am using hptuners standard to tune with so I want to put my wide band threw the ecm. Is the green connector #14 RED/BLK A/C Refrigerant Pressure Sensor Signal wire to my output of the wide band the only wire I need to leave to read my wideband signal? Or should I use one of the downstream 02 wires since they will already be long enough but will it accept a 5v siganl in?
