Is there not a way to put the Explorer's PATS module on his existing column? Much easier to retain his current lock cylinders.
Ranger850:
Correct me if I'm mistaken, but the truck you are upgrading is an '01 Ranger Edge.
PATS:
Assuming the truck above, you open the glove compartment, undo the ?2? nuts holding the airbag in place, pull out, disconnecting airbag wires. Then the PATs module is right there, unbolt disconnect and tape to the 3.0 ECM.
Ignition tumbler:
Put key in ignition switch, push fuller 807 phillips screwdriver in the secret hole on bottom of steering column and push in the lock. Turn key and presto, the tumbler falls out in your hand.
Door cylinders:
Pull the black tab that holds lock cylinder in place at back edge of door out. Pull lock cylinder out of door (needs a little manipulation to pull off lock wire). Repeat for door on other side.
Repeat same process to get the ones from the Explorer.
Reverse to reinstall:
Insert the Ignition tumbler in Ranger column, turn to off and tumbler locks in column, remove key and put in safe place. Attach the PATS module in the dash, bolt up, drop airbag module back in, bolt up, close glove box. If you are really good, you can reattach the door cylinder to the lock wire without having it fall inside the door*. With wire attached, push door cylinder into door and push tab back in. Repeat for door on other side.
*If you lose the wire, you have to remove the door panel to access. But then you were planning on upgrading the door speakers anyways, so you intended to remove the panels anyways.
Enjoy tall cool one.
