2001 Ranger 5.0 wiring

[DeepCDiver]

Need some help! I have swapped in a 2000 5.0 into a 2001 Ranger XLT 4.0 liter 4x4 and I am having problems with the wiring. I would appreciate any help, links, pictures, etc. I followed a wiring write up that I found form here but I can't seem to get the PATS module to work correctly. The dealer went to code my keys and said that the PATS is not working correctly. The computer is comunicating fine but he said I would know when the PATS is working correctly when I see the theft light come on and start blinking. Right now I already checked the wires for any problems and they are all good I just believe that I might have a problem with the write up that I used. The write up I was using was the one from Nathaniel V hunter and his vehicle was a 3.0L and I don't know if this makes a difference or not but it was the only write up I could find and was very well written for a 2001 ranger. I have even tried another PATS module and PCM but have the same problem. Ok thank you guys for any help you can provide.

Maybe deleting the PATS would help.

I don't believe I've ever seen that write up by Nathaniel V hunter. The 2001's are different from the early ones. This is the best wiring write up for the 2001's that I know of. It's over on RPS. Hope this helps. Dave

2) Rewiring The PATS System:
Both the explorer and the ranger have a different style of PATS system, rewiring is necessary to fix this.
the explorer has PATS type “B”, under this system, the key sends a signal to the PATS transceiver, the transceiver then sends a signal to the PATS transponder (PATS module), and this then sends a signal to the PCM that tells it that its ok to run. 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.
Starting in 2001, the rangers began using the PATS type “E” system. The way that type “E” PATS is different is that it eliminates the PATS module (transponder) by integrating it into the PCM. Under a type “E” system, the coded keys send a signal to the PATS transceiver, the transceiver then takes the signal and sends it directly to the PCM where it checks to make sure that the key code is correct and then allows the motor to run. Under the type “E” system, if the PCM fails to detect the properly coded key, then it will do two things. First, it will not send pulses to the injectors to cut fuel to the motor. Secondly, the type “E” system has the starter solenoid grounded in the PCM, if it doesn’t receive the proper signal it will not ground the starter solenoid which keeps the motor from cranking when the ignition is turned.
Obviously, because we are using the PCM from an explorer with a ranger body harness, when you do the swap he PCM will be looking for a signal from a module that doesn’t exist. When you have the motor in the truck and you excitedly turn the key for the first time not only will it not crank (because the starter solenoid isn’t grounded), but even once you do ground the solenoid and get it to crank, it won’t fire because the injector aren’t firing.
To fix this, an Explorer PATS module must be wired into the truck. This will require a different transceiver and key because the two different PATS types use different transceivers and keys. The wiring is almost all done on the main interior harness which is located behind the dash on the ranger, the steps are as follows:

…steps one through eleven are performed on the ranger main interior harness located under the dash.

I: add a tn/og wire to pin #9, circuit 914 on ranger connector c146, it is run the the explorer pats module

II: add a pk/lb wire to pin 10, circuit 915 on ranger connector c146 to be run the explorer pats module

III: disconnect the wh/lg wire, circuit 1215 and the gy/og wire, circuit 1216 from ranger connector c144, they are run to the explorer pats module

IV: disconnect the bk/wh wire, circuit 570 from ranger connector C2097(pats transceiver), its going to be run to the explorer pats module

V: disconnect the rd/lg wire , circuit 16 from connector C2097 on the explorer, its going to the explorer pats module

VI: jump the wh/ye wire, circuit 1001 from C220c (instrument cluster) on the ranger, its going to the explorer pats module

VII: disconnect the db/lg wire, circuit 343, from connector C144, its going to the explorer pats module

VIII: Disconnect connector C2097 (pats transceiver) from the ranger, it is to be replaced with C221 (pats transceiver) from the explorer. Circuit 1215 (pin #4) and 1216 (pin #3) are in the same position in connector C221 as the were in C2097

IX: connect a bk/ye (circuit 651) wire to pin #1 on C221 and a dg/wh wire (circuit 936) to pin #2. they are to be run to the explorer pats module.

X: All the wiring for the PATS module should be completed at this point, you should be able to plug in the explorer transceiver underneath the steering column (around the lock cylinder) and plug the explorer PATS module in to the connector that you just wired into the system. You need to find a place to mount the module, I just crewed mine into the plate that goes underneath the steering column.

XI: A new key is needed as PATS type “E” and “B” use different base keys, if you were unable to get one from the explorer you took the parts out of, you can go to a ford dealership and have them program one in using the factory protocol for programming a key to a 2000 explorer.

…the final step in done to the engine bay harness, this step is grounding the starter solenoid so that the vehicle will crank when you turn the key…

XII: disconnect db/og wire, circuit 325 (starter relay control) from pin #28, C110 on ranger harness, connect this wire to ground terminal on the battery

…now that the new PATS system is wired in and the starter solenoid is grounded TURN THE KEY AND LISTEN YOUR BEAST FIRE UP FOR THE FIRST TIME . Your truck is almost done, it’s at a point where it will run and drive but the speedometer won’t work and the check engine light will come on. Fixing this problem is addressed in step number three.

Only problem is that you have to have the PATS working correctly to delete the pats program and if I got it working then I would just leave it alone. The write up that Mac posted is the one that I used but I can't seem to get it to work.

Do you have any pictures or a more in depth description of what kind of plugs it needs or has and what wires are which? I’m doing the same swap on my ranger

Unfortunately, that user hasn't been active on the forum since 2013. You would be better off starting your own thread. Give all the pertinent info - what vehicle you have, what vehicle did the engine come from. Are you using the key, switch and PATS from your original vehicle or from the donor vehicle? And exactly what problems are you having getting it to work?
