Im trying to install a CD player in my Stang, and i checked to see if it worked and all and it did. But i was looking at the wires and they need to be connected stronger, someone was in there before and the wires were all cut and stuff, anyways i redid them all all an now it doesnt work, also the dome light and the map light decided not to work as well, ive checked all the wiring to the radio that i touched everything matches up. I checked all the fuses and none of them are burnt. What can i do, more importantly what did I do? What does it sound like happened. Should i disconnect all the wiring to the radio and try reconnecting them???
