If you know someone that works for a Ford Dealer they should be able to get it done but I think the computer needs to be in the vehicle and power applied.

Another thought, will a standard scanner do it ?

Have you checked with your local Ford Dealer ?

I'm almost positive you could use a computer from a 96-97. The only thing I'm not sure about is those years run on different fuel pressure with a return line and they have different heads. But I don't think that should affect the computer.

Realistically though, if your doing a motor swap, $250 to run the ecu that's for that motor is worth it. If you don't want to use pats, get a motor/ecu from the right year explorer.

A lot of good information here http://www.therangerstation.com/tech...er_ranger.html

The fuel pressure is different like said avocet and the 97 has a return line so fuel rails would have to be swapped just easier to do a pats delete there is ppl that can burn you a chip for the delete or take it to ford or buy a handheld tuner that you can program it out with

Getting a 96~97 5.0 PCM to work correctly with a 99~01 5.0 engine involves swapping/modifying a lot of stuff:

PCM
Injectors
Fuel rails/regulator
Return line
Engine harness
Synchronizer/CMP sensor
MAF sensor / IAT

Also, if running a 99 Ex 4R70W automatic, the Digital Transmission Range Sensor and the 99 transmission harness is incompatible with the 97 5.0 PCM. The later transmission also has internal mechanical differences - not sure if that's an issue or not.

One more - the logic to enable AC compressor operation is completely different 97 vs. 99. This would require a rework to make AC functional.

Those are some issues that I can think of off the top of my head. There may be more.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To the best of my knowledge, there is no Ford dealer tool that can eliminate PATS.

An aftermarket flash tuner like Sniper or SCT should enable turning PATS off but would cost about $400~$800 depending on model.

So I stand corrected, I always thought a Dealer could turn PATS off.

Ranger_Key, if Bob says it is so then I would believe him, he is very knowledgable when it comes to Ford Electronics.
In fact he IS the Electronics Guru around here.

What about, finding a used Early Mustang harness, that controls only the engine, and use it to run the engine in your swap, shouldn’t cost a lot used or from a JY.
The original harness from the vehicle can me thinned out and used to operate everything else in the vehicle.

Just thinking out loud, I use a 92 Stang Harness in my ’88 Ranger/5.0L setup.
Back then they used a separate harness for the engine control and another for the running of the vehicle so it was a piece of cake to do the conversion.
They sell new harnesses that do the same thing but we are talking $450 + to get a new one and you would need one of the 93 type computers also.

I was going to do a 5.0L conversion to my ’03 but now I am moving to SoCal I am not sure what is going on out there BUT IF I do it I will be using one of the FoMoCo Three Wire Conversion Harnesses, which is the same or very similar to the 90s Stang setup. ($450-600)

Luck on your task.

x2 on this.

Save yourself the headache and wait for a complete parts vehicle. Dont shy on traveling a bit, its worth it. Spend the time and money now, and it will probably get done quicker and cheaper in the end.

I do not know all of the parts needed but you will need the donor vehicle engine harness and computer, I believe the PATS is part of the Computer.

For a type “B” system, if the PCM does not receive the “ok to run” signal from the PATS module, then it will still allow the motor to crank, but it will not send pulses to the injectors cutting all fuel.

PATS Parts needed for swapping an Explorer 5.0L PATS type B in to a Ranger PATS type E:
1. Grab the module behind the passenger air bag
2. Grab the transceiver around the ignition lock
3. Get all the wiring that you can reach between the two
If you're swapping in to a non-PATS Ranger you'll need the Explorer's steering column.

Have you checked craigslist and other local private sales? I found mine on craigslist , i waited within a month, $500. Find a friend with a truck and a trailer and go on a little road trip if you have to.

People have pieced all the parts together, but just about everyone says they will not do it like that again. Even rwenzing, and he's as good as anyone. I'm not saying you can't, I just want to give you a heads up.

There is an online junkyard website, that searches all of the country's junkyards inventory. I'm sure you could find the right computer and parts and have them shipped.

I was going to suggest this. I don't know if your truck is PATS or not, but if it is, it's really simple to do this. If you don't already have tilt steering, I'd just go ahead and grab the whole steering column.

Careful with the tranceiver around the ignition cylinder. The tabs are easy to break off.
