Need help with PATS
Hey guys,
I'm going to be putting a 4.0 SOHC from a 2001 Ranger Edge in my 2004 Ranger XLT.
When I get to the PATS, what all is involved in that? I know that I have to switch the ignitions and the transceiver modules on the columns around but is there anything else I need to change?
How do you take the steering column apart to remove the ignitions? Is there any special tools needed to do this?
Thanks in advance,
Brian

Not sure on the actual PATS stuff, heres how to remove the steering wheel though.

Going across years with engine swaps is always risky. I thought I had researched everything when I did my swap and still ended up with a couple of headaches before I got through it.
The wiring to the PCM is different between 2001~2003 and 2004~2006. The biggest difference that I saw is the extra downsteam O2 sensor in the 2004+. That means not only extra wire inputs to the PCM but also a different PCM calibration for the P0420/P0430 catalyst efficiency codes.
To make matters worse, the 2004+ cluster uses a digital odo and onboard microprocessor that the 2001~2003 didn't have. That means that your 2004 cluster is in the Module Communication Network and is probably talking to the 2004 PCM. I have no idea what the implications of that might be.
If I were doing the swap, my best option would be to start with a 2004 4.0 engine, engine harness, transmission and PCM. If it has to be the 2001 4.0L, my choice would be to use the engine harness and PCM from a 2004 4.0L after verifying that no hard parts changed on the engine between 2001 and 2004. (Of course, I'd also pull it down and replace the camchain tensioners before installing the 2001 engine. No way I'd drop the 2001 in without upgrading and risk pulling the engine out again.)
If you have an automatic, another potential pitfall of using the 2001 PCM is the transmission control. There may not be any difference in the hardware or calibration between the two years but who knows?

As far a PATS is concerned, there's not much to worry about, at least that's how it appears on the surface of things. Both 2001 and 2004 use the same basic Type E PATS system. So, in theory, you should be able to simply use the PATS keys that the PCM has been taught to recognize or have a different set of keys "introduced" to the PCM using a dealer calibration tool. Obviously, using your current keys would be a bonus because they also fit the door locks.
If you need to pull an ignition lock cylinder for a swap, just insert the key, rotate the cylinder toward "ON" and push a punch or other tool up through the opening in the bottom of the column to release it. You should be able to do this without removing the plastic column trim.
To the best of my knowledge, there would be no need to change the Transponder Module on the column. I could be wrong about that but I don't think so.

I have the doner truck, so that'll make things easier, but it looks like if I want to keep my 2004 cluster then I'll need to get a 2004 wiring harness and a 2004 ECM/Computer.
I like the looks of the 2001 cluster, I just don't want to change the whole dash out. (I'm assuming that the 2004 4.0 wiring harness will plug into my onboard microprocessor.)
Correct me if I'm wrong, but wouldn't it be better to get another computer and wiring harness anyway because the Ranger Edge has a 4:10 rear end and my 2004 XLT has a 3:55 rear end.
Wouldn't the transmission shift too early if I didn't change those things?

I think I'm going to go ahead and swap out the rear ends too. (I think the drive shaft is different on the Edge and I believe it would be better to have a 4:10 anyway)
I'm also wondering if it would hurt to get a 2004-2006 wiring harness and ECM from a 4X4.
I would like to get one from a 2 WD, but they might be hard to come by since there weren't that many 2 WD 4.0 SOHC/ auto drivetrains made between 2004 and 2006.
Would I get any trouble codes if I capped the wires off going to the transfer case?

PCM stands for Powertrain Control Module and that has been the official name for the Ford engine and engine/trans computers for about the last 20 years.

This is very weird.
So, you mean to tell me if I got a wiring harness and PCM out of a 2005 Ranger I wouldn't have to worry about the PATS?
Would I even need to get the keys and ignition from the 2005 Ranger?

I'll be lookin high and low for a 2005 wiring harness and a PCM now.
If anyone has an extra one laying around let me know.
I'm also going to post a wanted ad in the classified section just for the heck of it.

You just made my day.
I'm guessing there's lots of 4.0 2WD autos out there too but I know there's more 4.0 4WD autos out there.
I'll look for the 2WD parts first and see what I can find. I just wanted to know about the
4X4 parts in case I have to use them but I hope I don't.

There are a couple of unknowns that you should keep in mind.
One is the engine assembly itself. For the most part, Ranger 4.0 SOHC engines should be the same across the board but there could be a sensor or connector or something else that is incompatible with a harness from another year. I'm not saying that there is but there could be.
Same thing for the 2004/2005/2006 harnesses. I could not say positively that these are all plug and play interchangeable across all 3 years although they might be. Like I said before, going across model years with mods has a certain degree of risk and the problems are often not apparent going in.
