Radio issues

[weezzell_5400]

I'm not new to wiring radios at all ...but this one has me stumped ....its a 1999 chaparral 1930ss ....the radio is a standard pioneer from walmart ....I know the 3 power wires being black red and yellow usually for ignition ....so that the radio comes on when the key is on.....well I can't seem to get power from what I assumed was the ignition wire..yellow...and there is also a orange wire that I can't get power from.... anda blue and white.I know what that one is for....all the other wires are speaker wires...can anyone help me on these wires....there was no radio in the boat when I got it...and can't seem to find a wiring diagram specific enough

unless you have a battery switch, tie the red and yellow together to a switched power source. that way your battery wont be dead in a few weeks
