I am putting a 05 5.3 in my 55 chevy using a stripped down stock harness with a/c rear 02's 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 is there a better choice like downstream 02 wires since they will already be long enough not sure if they accept a 5v referance or not?

You can also use the fuel tank pressure input for the wideband as well.

You can use any 5v reference signal that you removed from the original harness. The a/c wire would be fine.
