'93 dodge shadow wiring problems

I have a '93 dodge shadow and i tried to connect a newer stereo. I tried the cut and splice method but now my brake lights and turnsignals will not work. just need a little help on what wires to connect were.

hmmmm i dont kno where you cut and spliced the wires, but when i installed my head unit i seemed to have no problems i simply removed the old stock one and cliped the old connecters off and soldered the new one on. ill make a copy of the stock wiring chart colors if u need furthor help.

Also i have wired in a sony explode 500 watt amp with 2 8" subs in the trunk. and i replaced the old stock read speakers with 2 pioneer 5x9's 150 watts.. i wanted to go all pioneer but i got the subs n amp for free.\
