jontsp Posted March 18, 2009 Share Posted March 18, 2009 Hi, I need to install an lcd into my car and it has a Ground Wire and 12V Wire and i need to know what to splice them to? So i kind of need a Wire diagram. Any help is appreciated! Thanks! Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted March 18, 2009 Share Posted March 18, 2009 I don't think you need an electrical diagram for your car. All you need is a test light to find a 12V and it shouldn't be difficult to find someplace to attach a ground wire. For example, if you attach to the wire for the accessory (cigarette lighter) circuit, both a 12V and a ground wire are in the same cable. You could also attach the 12V to the underdash fuse box using an "add-a-circuit" fuse -- they are made for powering add-on accessories. See attached photo.
