if my stero is not wired in correctly can this evect the lights and the heating system in my car

It might - it depends on what happened when the stereo was put in - did everything work fine until the stereo was fitted and then things not work properly immediately afterwards ? If the answer is yes then the answer is yes.
If the answer is no then the answer is probably not.
