Thanks for the input everyone.
I'll try to give all the information. Sorry for being incomplete in my previous post.
All 4 doors see 12v- when they are closed, when they open they go to nothing. None of the switches drive anything right now, there is no load on them.
I need to...
Thanks for the response Mr. Zimmerman. Your idea looks simple enough, I think I'll give it a try. I do have a question though...
After I make the connections and have each circuit switching to 12v when the door opens, would I need to diode isolate each door at the point where all the outputs...
Hi. I have an odd situation and I hope you guys can help me out of little jam. I'm working on a car that has a door trigger circuit that needs to turn on some lights, but each door circuit rests at ground and switches to open when the door opens up. This would not really be an issue if I wanted...
