Did you get the proper reciever harness?Or did you get one at all?
Found two that is made for your year.
See if any of the two are similar to the plugs on your stang.

This one is for a factory amp set up.

When it comes to the factory amps,it's hard to get around it.
But a harnesses like the ones above make it easier,and have no guess work.
Don't know about the dashlights,how did you wire the stereo in?

 

As said above, get the proper harnesses and everything should work just fine.

 

i got the proper harness but i think i connected one wire that i shouldnt have so it leaves the dash light on but not sure wich so im gonna try them one by one i guess
