I installed a sony xplode cd player in my truck a while back.When I hooked the battery back up the radio worked fine but now I have no illumination lights in the truck at all.I have no lights in the instrument cluster or the climate controls as well as any of the buttons for the 4wd.The only lights at all are the interior lights in the ceiling.I also pulled the camper for the first time this year and noticed my tow/haul won't come on either.All of my gauges are working fine and I have tested all the fuses and they seem good to me.Any help would be appreciated.Thanks in advance.

 

Retrace your steps when you installed the radio. It is very likely that you accidentally disconnected something or connected it to the wrong place.
