i bought my car with a full system.. i took out the head unit and was about to put in a tv.. but the tv didn't work.. so i was gonna just put my head unit back on.. i forgot how it was connected before i took it apart.. now i'm lost.. the problem is that there is no power now.. why are there 4 plugs coming from the car when there's only 2 coming from the wiring harness adapter thing... what might the problem be? straight lost right now.. and i don't have patience.. so i just walked away from my baby sc.. didn't wanna let my temper get outta hand and break my baby.. help please

 

I am going to redirect this to the electronics forum so you will get more replies. Thanks

 

I need you to show me a pic or tell me the colours before I can help you, and I need to know which head unit as well, year of SC300, and Pioneer or Nak originally.
