I am trying to hook up a myron davis bought from James and was wondering if the blue wire is positive or negative and also if the black wire is positive or negative so i can hook up the wires to the dvd player. Anyone have a service manual to check or know from hooking up there DVD? Thanks Travis

Blue positive; black negative.

Welcome trav2314.

Here is another thread for a Myron and Davis how to install.

It mentions that the blue wire was just tied up and not connected to anything. I did my own install and remember doing the same thing. I can't remember what that wire was for.

That Blue wire on the DVD Player is to supply Power to the Monitor. Some monitors have an "Auto On" feature that allows it to automatically power on when the Player is turned on. He's asking more about the wires on the Cig Lighter and the + is Blue instead of Red for whatever reason.

So, how did the Install go?? Did you get it all done ok???
