Im out of ideas please help

bump still need help

DRL's have nothing to do with the radio. Were the wires not connected the orange or orange and white stripe? If so, those are for illumination and dimmer, both of which do things based on ground or 12v trigger. If you short the wire it will cause the dash lights to go out, which may be on the same fuse as the DRL's but I doubt it. Do your dash lights work? If not, check fuses and make sure the wire is isolated in the dash. If they do work, it's unrelated.
