Long story short ... I had to re-wire the o2 sensor wires. Is it possible for me to actually switch (2) of the wires without throwing a code? The darn car starts now instead of blowing a fuse but it feels REALLY weird.

To confirm: The (2) black wires make no difference?

I may just end up swapping the other two wires for ***** and giggles.

Hey one black wire is ground for the heater and the other is ground to the ecu,,better make sure they are right or it could get ugly
