???

what Security System are you referring to?
Cadillac did NOT have "Factory Security or VATS" in "1991"

IF this is Aftermarket or Dealer Installed, please post Brand & Model Number
Otherwise you need to test the Ignition wires for Voltage +

Hi there. I am Cam. Without knowing the resistor, your best bet is a VATS bypass by NEWROCKIES. This module installs inlace of the factory module and sends a constant bypass signal out to the ECM so it will run.

In the owners manual they refer to it as a plug that has a code in it i nded to bypass that code
Customer: replied 1 year ago.
Where do i get one
Expert:  Gm Tech (Cam) replied 1 year ago.

http://newrockies.com is the only place I know of, but they come with support, instructions and everything you should need.

Customer: replied 1 year ago.

Expert:  Gm Tech (Cam) replied 1 year ago.

This is the only way to truly bypass the VATS security system.
