Long story short. I am helping someone get a 5.0l drivetrain working in a 1990 Bronco II. The donor explorer allegedly did not use a PATS key to run. I did see the donor explorer run and drive, I just can't recall what the key looked like. I was just wondering if PATS was optional equipment.
If the donor explorer did use PATS, my theory is I should be able to get the engine running as long as I wire up all the PATS components. I have the Ford electrical and vacuum troubleshooting book. Then, as long as I have the PATS key inside the Bronco II when I attempt to start it, PATS should be able to query the PATS key and to tell the PCM It's safe to run.
Is that theory sound?
