They should work if you can plug them in the cable ends or side splice them in.
What is the reason you want to do it?
Without sensors the fuel feedback signal is no longer controlling fuel injection and should make the motor run richer and have poor fuel mileage.
Good luck.

Without sensors the fuel feedback signal is no longer controlling fuel injection and should make the motor run richer and have poor fuel mileage running on fixed fuel tables.

Deleted the rear O2's for the catalyst efficiency monitor when I built my exhaust system (Lightning swap). The custom tune on it doesn't require them, but I still need the emissions monitor to read "Ready" (NJ inspection). Believe it or not, it doesn't change the fuel economy. I get 18 mpg highway, with or without the supercharger.

Correct, the rear monitors have nothing to do with fuel control.
You didn't relate to the rears in your first post.
Good luck.

Good luck with the custom setup.
Hope all goes well.
The mil eliminators came along many years ago in the mid 80s when there were no cat monitors.
The modified Mustangs and other fast Fords that used custom programmers sometimes ran on fixed tables depending on why they needed to do that with wild mods.
Even today, all control programs will revert to richer fixed fuel tables if the OX senors are unplugged.
Not known much is the fact that when the throttle is advanced above about 7/8 throttle angle, the TPS signal tells the PCM to go to the fixed tables anyway that richens up the fuel and ignors the OX sensor signals.
The sensor calibration never changed that much except the plug arrangement, until flex fuels cam along.
Then there might be changes unless the program uses a fudge factor added to the tables to handle fuel mixes other than straight gas or a mix with ethanol. Depends on the year as time progressed

If you are running a tuner, you don't need mil eliminators. Just use the old O2 sensors. The computer will read them, and then ignore the readings. If your tune is not ignoring them, then the tune is not set up properly. No point wasting extra money on parts you don't need.
