I have a thunder switch, but I'm using it to turn on my amplifier. I put a factory switch in after replacing the fuel pump, and then ALMOST replacing the computer.....The secret connection is, as I remember, listed in the service manual as unused terminal 5  on the computer, and it requires a 5v signal...thunder should have the wiring schematic to help you...

Do you still have that switch ?

no....There is a special circuit in the computer that MUST see the correct voltage in order to verify that the ignition switch has not been tampered with. This is hard won information that cost me a fuel pump replacement I didn't need to do. Go to the thunder manufacturing web site and see if they have installation instructions for their ign. switch kit, that will tell you which wire has to have a resistor in it to fool the computer.
