So I have some spare DICs and speedometers laying around and wondered if someone can tell me what wires/pins need to be hooked up to a power source in order to power them on outside of the car? I'm thinking about maybe making some decorations for my house with them. Thanks! (I know I could pull up the wiring schematics and figure it all out myself, but I'm trying to take the lazy route if someone already knows the answer )
