Brain Box ? Slang Term? Stupid

You need to purchase a subscription from

scan tool --to enter your vehicle VID # for the
new PCM

So you can not do it

My boyfriend replaced the key cylinder and steering column has a box It has wiring I need a diagram or how to wire it 1998 ford expedition xlt it cranks but doesn't start.??

That box is for the anti-theft system , he changed the lock cylinder . You need new PATS keys . PATS - passive anti theft system .The transceiver module communicates with the encoded ignition key. This module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the instrument cluster.
And the dealer is the only one that can program the keys . or a mobile lock smith .

How do I program my new ingition switch in my ford expedition

Usually you'll start by turning the ignition to the on or accessory spot, it may require you to pump the gas or brake one or more times, but the new switch should have come with programming instructions. If you got it from advance auto or something, they can give you a printout on how to do it.

Replaced the brain box,but still wont start

Yes unforunatly, unless you know of a good repair shop that has the proper equipment. The thing is you vehicle may run with just a junk yard "brain box" (powertrain control module or PCM) but it wouldn't have the correct info in it (VIN gor that vehicle or mileage etc...). WWhat's cuasing the vehicle not to run is the anti theft. Your vehicles keys have a transpoder or chip in it that goes to a "brain box" (Sentry key immobilizer module or SKIM) that in turn sends a signal to the PCM telling it that nobody has just broke into the ignition switch and is just turning it with a screwdriver or something. There is really no way to bypass it either. Wish I had better news but I hope this helped

Reset security

I would not want to give you the wrong answer, but you need to be more specific about which component you replaced.
The tumbler would not have the same effect as the brain for the Security system. There are procedures for Coding a new Keychip to an established system and you would usually use one good Coded key to make a duplicate with certain button pushing combinations.
But to put in a different Brain, I am told, is a Dealer procedure to imprint and match the Brain and the Reader. Your old keys would need to be wiped and updated.
Since a Holiday Weekend is approaching, I wanted to give you some time this week to call the Dealer about this. Some other Expert may have more for you, but our suggestions will depend on which part you changed.
