4.6 in 41 Ford

If possible, go for buying a wrecked one and get all the harness etc, work a deal with the yard to buy back the car after you get what you need. Some will give you a lot better deal that way.
Dont know of any special keys required to put out the computer wiring system.

The keys I think you are refering to would be the "PATS" keys. Thats the ign. key with a transmitter built into it. No one can duplicate your key and use it to start your car unless it has been programmed into your PCM. A sensor is built into the lock cylinder housing that sees the programmed key. Only a dealer can program in the keys with Ford only programming equipment.

So I guess what you are saying is that I dont really need these keys. The PCM can probably be reprogrammed to get rid of this problem.

The keys have a coded chip in them to match the on board computer, no match no start.

Does anyone know of a way to disable this or a way to make it work in my 41?

At the time I left the Ford L/M dealership 3 years ago, there was not an option to disable the PATS system by reprogramming the PCM. If a key wasnt programmed into PCM the car would not start. That may have changed, you would have to contact your ford or L/M dealership service dept and ask. The problem I have with these systems is if you lose a key on the weekend, or change your PCM...... you gotta problem till you can get to a shop with the tools to reprogram the PCM. At the time when I was doing that, there was a 45 minuite delay built into the reprograming tool (NGS) so nobody could get a key made real quick and use it to steal the car (government regulations) and the shop charged for the time used to sit and wait for the reprogramming!!! Dont get me wrong, its not impossible, but its just a little easier to use non OBD II electronics from 94 and earlier cars. (EEC IV)

There is always the option of removing the transponder from the key (about an 1/16 inch black plastic square on the top of the key), and glue it to the receiver ring in the lock cylinder. Then it would be permanently attached to the system and if you had to reprogram the the PCM it would already be there. You could then have standard keys made for your car.

I have done a lot of research on the PATS system. Does anyone know if the transponder in the key talks directly to the computer or is there intermdiate circuitry in the dash that sends the ok to the computer? When I bought this engine I got the computer and all harness's that pertain to the engine. I was thinking that I could remover the transponder from the key and hardwire it so its always present. Then I could use a regular key and the computer would be satisfied.

Thanks,
Mike
