[BowTie Eater 5 Liter]

need help asap on this, i ordered o2 sensors for a 95 mustang 5.0, and all the parts stores and everyone are trying to tell me that this motor had 2 pre cat and 2 after cat sensors, which is incorect.

the ones i got were ntk 22016's, which do not fit in the harness. the harness has a 4 pin connector but only 3 are used.(and the plug is different)

i ordered o2 sensors from a 93(after i got the incorrect 22016's), which is the right connector, but the parts guy said that it only has 2 wires, and i believe i need three.

does anyone know the exact, 100% for sure way to get the right sensors?

i have to get them today, because my truck is coming home tomorrow and driving it without any o2's is going to be obnoxious.

thanks for the help, Kris.
