Re: how to remove the security system
To completly remove or disable the VATS system would require a PROM that is programmed appropriatly.
Doing a search on the subject will show you more details.

Re: how to remove the security system
On a third gen you can physically bypass the VATS module with a wiring jumper.
I had to do it on my 91 RS when I put a non computer controlled engine into it.
If I remember right it was a 10 or 12 gauge purple wire coming out of the VATS module and a red wire of matching gauge coming in and I just had to connect the dots.
There is a mechanics bypass harness that the dealer uses to trouble shoot VATS issues and this just mimics the same thing their jumper harness does but permanently.
