So am looking at the post that orge has on the blue dingy thingy he shows some information but i am looking past that information and looking for what else is happening at that time for a project.

idea of the project taking a switching recordable usb module and when each button on the module is pressed it says something like "lights are on" since each circuit on the fiero when it comes to

pin a lights gets 12v then i would have a npn transister to complete the circuit to press the button
pin d for the parking brake gets 0volts when on and use a pnp transister in the circuit to press the button
pin e for key in the ignition gets 12v when key is in ignition and the door is ajar so i would use a npn transister in the circuit to press the button
pin h for fasten seat belts gets 12v when the car starts up to remind you to plug in your seatbelt you would use a npn transister in the circuit to press the button
pin b is 12v always on
pin g for ground

Am i missing something to my reasoning?
need some help the buttons have 4.5volts connecting the circuit on the module i am installing what can i put inline to ensure 12volts does not go into the control board? run a voltage regulator for each button?

"Your door is ajar" - Right door
"Your jar is a door" - Left door

the circuit i am working with has 4 buttons the next will have 6 and do trunk or lid, right door, and left door.

Is there any kind of aftermarket item like this available already? Something some what universal that would tell (voice) me when my lights are on or door is ajar, ect that I can wire into my lambo kit car? I know they make these voice "add on" units for car alarms, and I think I remember something about some kind of unit when a factory radio/amp is replaced in cars that have OEM voice alert..?? I dont have the motovation to try to do something like your project...

Some 80's Chryslers had that feature.

After people got tired of hearing "Your door is ajar" (NO - it's a door!) most people disabled them.
After the first 10,000 cars, Chrysler added a hidden OFF switch.

if you look in the original irm catalog there was one that was sold. This is again an exercise for electronic skills i am going to build one for my self it is something that i want.

I do remember seeing little modules in a car parts store that could be wired to lights, oil & temp gauges before. I havent looked in years and dont know if theyre still around.
