I am trying to hookup a Lowrance Elite 5 chartplotter gps fishfinder combo to a Uniden oceanus DSC marine radio. My gps combo acc. cord has a yellow , orange and black. my radio dsc has green, brown, red, yellow,and a bare wires. I think the yellow from the gps and the green(data in)from the radio hook together. the Question is what does the black from the gps hook to. The tech from Harbour Chandler said he thinks it hooks to the brown radio wire. The diagram he used was from a Uniden Solara not a Oceanus. The Oceanus manual says the brown is PA(+) Appreciate some input Thanks Dwight
