Yeah so i pulled the motor and replaced it over the past few months and finally reconnecting everything (90fox). I can't for the life of me figure out where the o2 sensors plug in. I can't find the damn harness anywhere under the car near the sensors. I labeled all connectors except ones i thought were obvious....but i can't find these. does the harness come down from the firewall or up from the trans area? yeah i feel like an idiot because this is the 5th mustang i've owned and i can't even figure this out...lol.
