i have a deh-p2050 pioneer head unit and i need to find a wiring diagram for it was one of the wires came unconected and now it dosnt work so dose any1 here have a manual or something that could tell me or know of a web site that will tell me i tried searching on car audio australia but didnt find anything. or maybe if some1 who has one of these headunits could have a look and tell me which pin the red wire needs to connect with (i duno much about car audio so sorry if this sounds supid and every1 had different colour wires or something)

general rule of thumb Red = battery Yellow = Accessories Blue = Remote (for amps) Black = Ground paired colours = speaker wire (trial and error to find which is which as far as fron, back left, and right are though) that should be it

thanks for the help found these colour guide things on the net just after i posted it andgot the multimeter out and fixed it in a half hour thanks anyway.
