Did not use a control pack. All wires and components came from the 2013 coyote and the front and rear harness was partially from the 90 foxbody.Sorry to bring this up but did you use a control pack ? Did you get it tuned through a tuner or did you have ford provide a stock tune for smog ? Did you run all 4 o2's?
Although I had to have Ford reflash the stock tube back into the ECU, it was only because it was off the battery for over 9 months.
Yes smog ref required proof that the tune in the car is the original tube.
I used all 4 O2 sensors
