I've got some sweet neons that look great mounted under the dash (both sides) and right now, I've tapped into the switched lights that are there (the 194 bulbs that turn on when you open the doors). What I would like to do, is wire this so I can have a switch turn on the neons, AND have them turn on when the doors open.
Below is a rought schematic that cowgod wipped up:
I'd wire it like this, but I also want these things to light when the doors open too (another switched 12v source).
Any of you electrical guru's out there know how I could wire this properly, if its possible?
