Well, I am almost there. The USB charging port and fancy headlights work thanks to MrGolf. I have tested all wires and I have steady power throughout.

However, I do need help still with the radio. It is a cheap car radio with a red power, yellow ignition switch wire and a black ground. I have tried a couple options but they don't seem to work.

How do I wire the radio from the madjax 12v reducer? What do I do with the yellow ignition switch wire? Do I connect the radio black wire to the madjax negative or to a battery terminal?

Any ideas to finish this off would be much appreciated.
