thank you for responding
1. i would like to controll each relay individually and no more than two relays will have to be closed at the same time but the more that can be closed at the same time the better. here are the relays i am looking at

2. I am hoping to not have any cables running between the controller and the relay box. they will each have differant power sources.
3. I am not sure what you mean. I don't know much about electronics
4. The relays will be contolling power from a 12 volt car battery. They will be actuated by regular 9 volts. The controller box will run off whatever is neccesay for the radio.
Again, thank you. I really appreciate your help.
