Stereo connection wires help.?

Question

I have http://www.audiovox.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&storeId=10001&productId=1603134&langId=-1

this stereo in my boat, 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?

Answer 1

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
