Mitsubishi Repair: dashboard lights, dashboard lights, circuit connections

Question
Okay my friend was wiring my new car stereo after we were done the dashboardlights including the ac lights and the shifter lights didn't work and irts not the dimmer that's down and its not a fuse all the fuse are good. Can you help me? I think it might be a circuit if so how much would something like this cost me? Thanks

Answer
Leo,
Most dashlights are wired in series, so if there is one node that has been disconnected, nothing will work.  The previous stereo most likely was part of that circuit and now that you removed it, the lights will not work.  You can either figure out where those circuit connections were in the old stereo or have a stereo shop fix it. Unfortunately, I have no clue what this could cost you.
Good luck!
