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.
