Ha, yeah I do have rca outputs on the back of my dvd player. And I did order an indash head unit with am/fm and mototrized 7" monitor. And what I meant is only one red and one black from the dvd player. And attaching to the stock wire harness that goes in the the back of the stock radio is a red wire and a black wire. I'm just going to t-splice each wire in the haness and connect the wires with their respective colors. I think it should work...
