Your truck has the p.a.t.s. system. A cluster swap requires reprogramming

What it is: Passive anti-theft systems (PATS), like Ford's patented SecuriLock system, protect against drive away theft through the use of an electronically coded ignition key. The system is designed to help prevent the engine from being started unless a coded key programmed to the vehicle is used. An indicator shows the system is working.

How it works: A miniature transponder with an integrated circuit and antenna is embedded in the ignition key. A wireless radio-frequency transmission transfers an electronic code between the transponder in the key and the vehicle. If the code matches, a code programmed in the vehicle, a signal is sent through the wiring system to the electronic engine control, allowing the engine to start. There are 72 million-billion possible codes, so every Ford sold worldwide for the next 10 billion years could have unique codes. New keys for replacements or spares can be purchased at dealerships. A customer may program spare keys to the vehicle themselves if they possess any two keys that operate the vehicle. A dealership technician may erase and program keys using diagnostic equipment. A maximum of eight keys may be installed in most systems.

Customer benefit: Increased protection against drive away vehicle theft, where the thief starts the engine and drives the vehicle away.

Ford status: Standard on most North American vehicles in model year 2000.

Not to be a **** or anything, but what does a coded key have to do with changing out the dash? I'm honestly asking to learn. Also its for 2000+ he said 1999.

PATS was standard on 2000+ models. Higher trims got it as an option before that.

But, if you need the Cliffs Notes version, gauge cluster shoots signal to chipped key, which in turn bounces signal back to gauge cluster in under the length of time it takes to turn the ignition to start the truck.

If cluster signal doesn't like what the key sends back, truckie no startie.

Hence, the reflash needed when clusters are swapped..

The cluster is part of the PATS system. A replacement cluster has to be programmed to the PCM and the keys to the rest of the system.

You'll either need to re-install the old cluster or have the truck towed to a dealership if you want to get it started again.
