I am planning on engine swapping my automatic 1999 3.0 v6 2wd Ranger and throwing the engine from my 1997 5.0 v8 AWD Explorer into it. My question is about the PATS system I know the 1997 Explorer doesn't have a PATS system but the 1999 Ranger does have a PATS system. What will I need to do when it comes to dealing with the PATS system? Will I need to put the explorer steering column into the ranger?

 

No, on the steering column unless you want to, but nothing to do with PATS

If you are keeping the Rangers engine bay fuse box then you will need to Ground the Starter relay in that box

1999 Ranger PATS wiring blow

PATS module is above the Glove Box
16 pin connector

Pin 1 the pink/orange wire is the Ground for the Starter Relay in engine fuse box

I would unplug the PATS module since it has power all the time, one less thing to drain a battery
And cut and ground that pink wire in the dash or to pin 7 ground wire, and thats about it


1999 PATS works by reading the key in ignition via Transceiver, which is just an amplified antenna
PATS module then compares the key number to its list of 3 or 4 keys programmed in at the factory
If a Match is found then the PATS module grounds pin 1 and sends the 1999 Computer an "OK to Start" message

If no Match then no ground and no computer because no message

So without the 1999 computer and PATS module there is NO PATS.......................except for the Starter Relay being grounded

 

Thank you, man. You are awesome.
