Yes sounds similar to newer models. Once you locate power source to these loads. Turn on maplights, power something in socket, and iI think the radio can be powered here from same fuse. If the voltage is 12-13 volts and nothing of the 3 works it could be a common ground connection problem. If voltage is lower than that, fuse holder or power wire problem. All those devices come from a always hot bus.
Reason to load the circuits is a battery will show ful lvoltage across a bad connection. However when load is applied, it will drop like a stone
