Hi it was the factory one. Dealership Forman with 41 yrs experience managed to shut it off but it burnt the ignition regulator in the distributor.

Hey
I've had this issue in the past.
One way that worked was to remove both contacts from battery and attaching them together for about 20-30 min. It'll reset the connection.
Another reason could be that your ground is not fully contacting and causing the security to repeatedly reset.
Hope it helps

If you want to keep and work on this car, then you need the Factory Service Manuals. They are the best investment you can make in your car. Not optional IMHO.

Thanks for the tip. So far it is ok. My only other issues are a blend door and the radio keeps blowing fuses.

The blend door gets sticky after burns fuses due to constant stress on the motor. If you open under the dash and clean it, it should fix the issue. Hope it helps. I don't know why the radio is burning fuses though.
