a little bit of help please
ok, well, i scored a concept CM-701N 7" flip down monitor from one of my friends about a week ago. well he forgot to give me the wire harness for it out of his old car which got totalled. well, im gunna hook it up pretty soon, and theres 4 wires for it, Yellow, Black, Blue, and White. Yellow (possitive), Black (ground), but i don't have any idea what the white and blue wires are for and/or how to hook them up. anybody have any ideas? he said if you just twist them together it works fine and all, but that doesn't make sense. if thats what it did in the harness, they wouldn't spend the money on making the wire that long ya know.
so can anybody help me out here?
thank you mucho
