its an older boat without fuse box, if you go to the manual on the website it gives you the wire layout. I know the radio works but a friend of mine disconnected the wires to try to put a switch in and never reconnected them. I don't know what to do with the ground wire or the red wire. Any suggestions?
the ground wire black is connected to -ve of battery the red wire is connected to ignition wire so when you turn on the keys the radio starts the yellow wire is connected to +ve of battery, but radio will not switch on till red is connected. good luck
