Until someone comes up with a diagram,

With 2 sw does this mean you want one sw to supply power to what is supposed to get power when key was turned on AND the other sw to activate the starter ?


If so, do you have either a volt meter, or test light ?

Hi Ken,
You bypassed the mechanics of the security system, but are overlooking the electronics of that system.
The functionality of your vehicle's system is controlled by the PCM.
What happens if you leave the key in the on position when you use your by pass to start the engine ?
That might satisfy the security system which you have not replaced.
By the way, that system still requires a coded key to get that light out .

Just out of curiosity, you have 2 vehicles you are getting involved in, and keep in mind their systems are very different and what you do with one will not work with the other, OK.
