Long story short... VATS is dead/bypassed, looking to install a kill switch to disable the starter and/or spark/fuel.

Which wire should I put my switch on? Coming down from the column, here are the choices:

Red
Red with White stripe
Orange
Yellow
Pink
Light Green
Dark Green
Tan

I'd prefer to just kill the ignition circuit altogether so that when the key is turned to START, nothing happens. I've looked at all the diagrams and still am unsure which one to use, so I'm asking here to be sure. Thanks in advance.

Tie into the vats wires that you bypassed and make it so the system can't see the resistor.

At first I didn't think that would work because the security light remained on after the bypass, leading me to believe that the VATS system was disabled because it "found an error with itself". After driving it for a short trip, the light went out.

After further testing, the system seems to have recognized the bypass as me "fixing" it. Installed the switch in there to hide the resistors, and it works as intended.

Thanks again Bill.

No problemo.. glad to help.
