PATS E in a PATS B Truck

I am in the middle of dropping a 29K motor into a 99 B3000, therefore a 99 B2300 after done. Problem is the motor came out of a 2002 Ranger (PATS E) and the 99 B3000 (PATS B)

So my question is, since the 99 has PATS B it has a module, can I just jumper this connection or leave it blank when switching all PATS E (ECU, TRANSMITTER) to the 99.

Also it is going from a 99 B3000 AT to a 99 B2300 MT, where do I source the clutch neutral plug also?

Just to be clear:
You have a 2002 2.3l Duratec 4cyl engine, with manual trans, and the computer and wiring harness for it.

You are removing a 3.0l engine with automatic, and its computer and wiring harness.

You may need "the wand" wiring for the 2002, it would plug directly into computer harness, since PATS is in the computer not a separate module.

Since you are switching from auto to manual you might as well pull the '99 steering column out, then change the pedal assembly and put the 2002(manual) steering column in, it will have the "wand" and wiring and the correct PATS key match as well.

The Clutch switch connector is there under the dash, it will have the Automatic wiring "By-Pass" plugged into it, just unplug the Automatic wires and plug in the clutch switch

So far I have changed the column and pedals. I just have been wrapped up hoping that I can solve the only thing I hope is keeping me from doing the swap is the Pats E in the B. Had no luck finding/understanding what the wand means.

To pick up the PATS key's RFID tag in the handle the ignition key cylinder has a flat antenna "loop" around it, also called a "wand" because of what it looks like, or ring or transceiver.

The wand connects to the PATS module above glove box on a Type B system, on Type E the wand connects directly to the computer.

When the key is turned on the wand sends an RF(radio frequency) burst, this gives the PATS key enough power to send out it's unique RFID(radio frequency identification) number to the wand.
PATS module(type B), or Computer(Type E), read this number and compare it to a list of RFID numbers that were programmed into it's memory at the factory, if a match is found then computer will allow engine to start.

So what you need is the wiring for Type E wand direct to computer, vs the Type B that would go to separate PATS module

The wand, ring or transceiver is just an antenna, not specific to PATS type, just like the radio antenna on the fender or in the windshield, doesn't matter what brand of radio you have, antenna works with any brand.

Ohh I see, bc no connector available in my pats B truck, just pin out to the computer directly. Any info on where on computer... possible to salvage part of the B wiring to use the connector to tap into computer? I just figure might be a way to jumper existing PATS module pins that head to computer.

Look at post #56 here: https://www.explorerforum.com/forums....php?p=3490051
That should be Type B wiring

The post #227 here: Everything you wanted to know about PATS. - Page 12 - Ford Explorer and Ranger Forums "Serious Explorations"
That should be Type E wiring

PCM = power train control module, "the computer", also called EEC-V after 1994
Transceiver module is "the wand"

Google: ford ranger EEC-V pins

To see the pin numbers referred to in above drawings

2001-2003 ECU PIN 17 and PIN 18 from WAND PIN 3 and PIN 4 respectively
2001-2003 ECU tranplanted in 99 expects PIN 17 and PIN 18 from WAND PIN 3 and PIN4 (PATS CONNECTOR JUMPER 11 to 5 and JUMPER 13 to 6 and 16 to 10)
Only problem I have is if I put the wiring harness from the the 2002 2.3L with its computer is I will need to switch the pins where the connector from engine to chassis is I believe to guide it to pin out to the ECU

This is all to be tested, but waiting to land engine this week, then pursue PATS
